Product details
Overview
2SK3113-AZ from Renesas Electronics is an N-channel enhancement-mode DMOS power MOSFET designed for high-voltage switching applications, featuring RDS(on) = 4.4 Ω (max) at VGS = 10 V and ID = 1.0 A, 600 V drain-to-source breakdown voltage, and 9 nC total gate charge. It delivers low conduction loss and fast switching in offline AC-DC adapters and auxiliary power supplies.
For engineers reviewing the 2SK3113-AZ datasheet, 2SK3113-AZ pinout, 2SK3113-AZ application, or 2SK3113-AZ equivalent, key selection criteria include avalanche energy rating (EAS = 2.7 mJ), body diode reverse recovery time (trr = 0.9 μs), and TO-252 (MP-3Z) surface-mount package compatibility with thermal derating constraints on glass-epoxy PCBs.
Technical Context
This device uses a double-diffused MOS (DMOS) structure optimized for high-voltage blocking and low gate charge. Its gate threshold voltage (VGS(off) = 2.5–3.5 V) ensures reliable turn-on with standard 10 V gate drivers while maintaining robust noise immunity.
The integrated body diode exhibits forward voltage VF(S-D) = 0.9 V at IF = 2.0 A and reverse recovery charge Qrr = 2.0 μC under di/dt = 50 A/μs - critical for snubberless flyback and resonant converter designs where diode commutation losses dominate efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 600 V - supports primary-side switching in universal-input (85–265 VAC) offline SMPS without derating. |
| RDS(on) | 4.4 Ω max at VGS = 10 V, ID = 1.0 A - determines conduction loss in continuous conduction mode (CCM) operation. |
| QG | 9 nC typ at VDD = 450 V - enables efficient driving with low-power gate drivers and reduces switching loss at 50–100 kHz. |
| EAS | 2.7 mJ single-pulse avalanche energy - allows unclamped inductive switching in flyback snubberless designs without external protection. |
| trr | 0.9 μs body diode reverse recovery time - limits diode-induced voltage spikes and EMI in discontinuous conduction mode (DCM) topologies. |
| PT1 | 20 W at TC = 25°C - defines maximum steady-state power dissipation when mounted on heatsink or thermally enhanced pad. |
| ID(pulse) | ±8.0 A (PW ≤ 10 μs, duty ≤ 1%) - supports peak current handling during startup or overload transients. |
Pinout & Package
2SK3113-AZ is housed in a TO-252 (MP-3Z) surface-mount package with exposed drain tab for thermal and electrical connection. The package features gull-wing leads compatible with standard reflow soldering processes and provides 6.25°C/W channel-to-case thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives gate drive signal; requires ±30 V absolute max rating and 2.4 nC QGS for full enhancement. |
| 2 (Drain) | High-voltage output terminal | Connected to primary winding of transformer or DC bus; electrically tied to exposed metal tab for thermal path. |
| 3 (Source) | Reference node / return path | Serves as common reference for gate drive and current sensing; body diode anode is internally connected here. |
Key Features
| Feature | Design Value |
|---|---|
| Low gate charge | QG = 9 nC enables <100 ns total switching time (td(on) + tr + td(off) + tf) at 10 V drive, reducing dynamic loss in 65–100 kHz converters. |
| Avalanche-rated operation | Rated for single-pulse EAS = 2.7 mJ at Tch = 25°C - eliminates need for external clamping in cost-sensitive flyback auxiliary supplies. |
| Body diode with controlled recovery | trr = 0.9 μs and Qrr = 2.0 μC allow predictable commutation behavior in DCM operation without oscillation or shoot-through risk. |
| Thermal performance | Rth(ch-C) = 6.25°C/W enables 20 W dissipation at case temperature ≤ 100°C - suitable for compact board layouts with limited copper area. |
Applications
| AC-DC Adapter Primary Switch | Flyback Auxiliary Supply |
|---|---|
|
Use Scenario: 12 V/1 A isolated auxiliary supply in 65 W laptop adapter, operating in DCM at 65 kHz. IC Role / Device Role / Timing Role: Main power switch controlling energy transfer from primary to auxiliary winding; turns on/off at fixed frequency with variable duty cycle. Use Value: Low QG minimizes gate driver loss; avalanche rating absorbs leakage inductance spike without snubber, reducing BOM count by one resistor-capacitor-diode set. |
Use Scenario: Standby power supply in multi-output industrial SMPS, delivering 5 V/0.5 A to control circuitry during main converter sleep mode. IC Role / Device Role / Timing Role: High-side switching element in self-oscillating flyback topology; conducts during primary switch off-time to recharge auxiliary winding. Use Value: 600 V VDSS accommodates reflected voltage plus margin in 230 VAC input; low RDS(on) keeps standby loss below 150 mW at light load. |
| LED Driver Secondary Switch | Industrial Sensor Power Stage |
|
Use Scenario: Constant-current LED string driver for signage, using primary-side regulation with auxiliary winding feedback. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in quasi-resonant flyback, conducting during secondary-side voltage reversal phase. Use Value: Body diode VF(S-D) = 0.9 V at 2 A reduces conduction loss vs. Schottky alternatives; trr stability across –25°C to 125°C ensures consistent dimming linearity. |
Use Scenario: Isolated 24 V sensor interface module powering analog front-end and digital isolators in factory automation PLC I/O cards. IC Role / Device Role / Timing Role: Primary-side switch in miniature 5 W isolated DC-DC converter; operates in CCM with current-mode control. Use Value: RDS(on) drift <15% over –40°C to 125°C maintains regulation accuracy; TO-252 footprint allows automated assembly and thermal vias to inner ground plane. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STP6NK60ZFP | 600 V, RDS(on) = 1.2 Ω, QG = 16 nC, TO-220FP package | Higher conduction efficiency but larger footprint and higher gate drive demand; requires heatsink for >5 W dissipation. | Preferred for higher-power (>15 W) adapters where thermal mass justifies through-hole mounting. |
| IXTP50N10P | 100 V, RDS(on) = 0.022 Ω, QG = 32 nC, TO-220 package | Lower voltage rating precludes universal AC input use; optimized for low-loss 12–48 V DC-DC stages. | Only suitable for DC-fed isolated converters (e.g., telecom intermediate bus); not a drop-in replacement for 2SK3113-AZ. |
Compared with STP6NK60ZFP and IXTP50N10P, the 2SK3113-AZ offers optimal balance of 600 V capability, surface-mount TO-252 packaging, and moderate gate charge - making it uniquely suited for space-constrained, universal-input auxiliary supplies where thermal management relies on PCB copper rather than discrete heatsinks.

FAQ
What is the maximum continuous drain current rating for the 2SK3113-AZ at 25°C case temperature?
The 2SK3113-AZ has a maximum continuous drain current ID(DC) of ±2.0 A when the case temperature (TC) is maintained at 25°C. This rating assumes proper PCB thermal design - specifically, mounting on a 40 mm × 40 mm × 1.6 mm glass-epoxy board with adequate copper area. At higher case temperatures, current must be derated per the datasheet's PT1 curve; for example, at TC = 100°C, the usable ID(DC) drops to approximately 0.8 A. The 2SK3113-AZ must not exceed its 150°C channel temperature limit under any operating condition.
Does the 2SK3113-AZ include integrated gate protection, and what external protection is recommended?
Yes, the 2SK3113-AZ integrates a gate-to-source Zener diode for ESD protection, rated for ±30 V gate-source voltage. However, this internal diode is not sufficient for transient overvoltage events in real-world power circuits. Renesas explicitly recommends adding an external gate protection network - typically a 12–15 V Zener clamp from gate to source, combined with a series gate resistor (10–47 Ω) - to prevent damage from Miller-induced voltage spikes or layout-induced ringing. This requirement applies regardless of whether the 2SK3113-AZ is used in flyback, forward, or LLC topologies.
Can the 2SK3113-AZ be used in avalanche mode repeatedly, or is EAS a one-time rating?
The 2SK3113-AZ's single-pulse avalanche energy rating (EAS = 2.7 mJ) is strictly a non-repetitive, one-time capability - verified under defined test conditions (VDD = 150 V, RG = 25 Ω, starting Tch = 25°C). Renesas does not specify repetitive avalanche ratings for the 2SK3113-AZ, and repeated avalanche operation risks cumulative degradation of the DMOS cell structure. Therefore, the 2SK3113-AZ should only be operated within its SOA limits during normal switching; avalanche mode is reserved for fault conditions or unclamped inductive turn-off events, not for routine design margin.
What is the typical gate threshold voltage range for the 2SK3113-AZ, and how does it vary with temperature?
The 2SK3113-AZ has a gate threshold voltage VGS(off) specified from 2.5 V to 3.5 V at TA = 25°C, with typical value near 3.0 V. This parameter decreases linearly with increasing channel temperature - dropping to approximately 2.0 V at Tch = 125°C - which improves turn-on robustness at high temperature but requires gate drive circuits to maintain sufficient overdrive (≥5 V above threshold) across the full operating range. The 2SK3113-AZ's VGS(off) variation is documented in the datasheet's "Gate Cut-off Voltage vs. Channel Temperature" graph, confirming monotonic negative temperature coefficient behavior.
Is the 2SK3113-AZ RoHS compliant, and what is its quality grade classification?
Yes, the 2SK3113-AZ is RoHS compliant per EU Directive 2011/65/EU, as confirmed by Renesas' environmental compliance documentation. Its quality grade is "Standard", meaning it is qualified for use in computers, office equipment, communications gear, audio/video devices, home appliances, and industrial robots - but not for automotive, medical life-support, or aerospace applications unless explicitly requalified. No additional "Specific" or "High Quality" markings appear in the 2SK3113-AZ datasheet or ordering information, so users must adhere to Standard-grade usage limitations and obtain written consent from Renesas before deploying the 2SK3113-AZ in safety-critical systems.
