Product details
Overview
2SK3116B-ZK-E1-AY from Renesas Electronics is an N-channel power MOSFET designed for high-voltage switching applications including AC adapters and offline SMPS. It features a 600 V drain-source breakdown voltage, 1.2 Ω maximum RDS(on) at VGS = 10 V and ID = 3.75 A, 22 nC typical total gate charge, and TO-263 (MP-25ZK) surface-mount package with integral heatsink tab.
For engineers reviewing the 2SK3116B-ZK-E1-AY datasheet, 2SK3116B-ZK-E1-AY pinout, 2SK3116B-ZK-E1-AY application, or 2SK3116B-ZK-E1-AY equivalent, key selection criteria include avalanche energy rating (37.5 mJ), diode reverse recovery time (390 ns), and safe operating area under pulse conditions - all critical for flyback and resonant converter designs requiring robust unclamped inductive switching capability.
Technical Context
This device operates as a unidirectional high-side or low-side switch in hard-switched topologies. Its gate threshold voltage range (2.5–3.5 V) enables compatibility with standard 5 V and 10 V logic-level drivers, while its ±30 V gate-source rating supports robust gate drive margin against transients.
The integrated body diode exhibits 0.93 V forward voltage at 7.5 A and 390 ns reverse recovery time, enabling use in synchronous rectification or freewheeling roles where controlled diode conduction is required. Its 8.6 nC QGD and 11 ns rise time indicate fast, controllable turn-on behavior suitable for 100–500 kHz switching frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 600 V - Supports primary-side switching in universal-input (85–265 VAC) offline converters without derating. |
| RDS(on) max | 1.2 Ω @ VGS = 10 V, ID = 3.75 A - Enables <1.5 W conduction loss at 3.75 A DC, suitable for ≤40 W power stages. |
| QG typ | 22 nC - Low gate drive power requirement; compatible with low-current gate drivers like TC4420 or UCC3732x. |
| EAS | 37.5 mJ - Rated single-pulse avalanche energy allows reliable operation during overvoltage transients in inductive loads. |
| trr | 390 ns - Fast body diode recovery reduces switching losses and EMI in discontinuous conduction mode (DCM) flyback. |
| PT2 | 70 W @ TC = 25°C - High case-power dissipation supports direct PCB copper pour or external heatsink mounting in TO-263 package. |
| ID(pulse) | ±30 A - Supports short-duration current surges during startup or overload, critical for peak-current-mode control loops. |
Pinout & Package
2SK3116B-ZK-E1-AY uses the TO-263 (MP-25ZK) surface-mount package with exposed drain tab for thermal and electrical connection. The package has three signal terminals plus an integral metal fin acting as the drain terminal and heatsink interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives gate drive signal; requires <30 V absolute max swing and low-impedance path to minimize ringing and overshoot. |
| 2 (Drain) | Main high-side current path | Connected to high-voltage rail; electrically and thermally tied to exposed metal tab - must be isolated from other layers unless designated as ground-referenced. |
| 3 (Source) | Reference node for gate drive and current sensing | Serves as return path for load current and gate drive loop; layout must minimize inductance to preserve switching speed and stability. |
| 4 (Fin/Drain) | Thermal & electrical extension of Drain | Exposed copper pad on underside; soldered directly to PCB copper pour or heatsink - provides dominant thermal path (Rth(ch-C) = 1.79°C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Low gate charge (22 nC) | Reduces driver power consumption and gate drive loop losses, enabling efficient operation at >200 kHz without excessive driver heating. |
| Avalanche-rated (37.5 mJ) | Eliminates need for external snubbers in clamp-free flyback or forward converters subjected to leakage inductance spikes. |
| Fast body diode (trr = 390 ns) | Minimizes reverse recovery losses and associated voltage overshoot during hard commutation, improving efficiency in DCM operation. |
| High VDSS (600 V) | Permits direct use in 400 V DC bus applications (e.g., PFC output) and 265 VAC input systems with margin for line surges per IEC 61000-4-5. |
| TO-263 thermal performance (Rth(ch-C) = 1.79°C/W) | Enables >50 W continuous power handling with minimal external heatsinking when mounted on ≥2 oz copper with 4 cm² thermal pad. |
Applications
| AC Adapter Primary Switch | Flyback Converter Main Switch |

| LED Driver High-Voltage Switch | Offline SMPS Auxiliary Supply |
|
Use Scenario: Constant-current LED driver for street lighting using 48 V string at 700 mA, powered from 230 VAC mains. IC Role / Device Role / Timing Role: Primary-side switch in buck-boost-derived offline topology with active PFC pre-regulator. Use Value: 600 V rating accommodates PFC output ripple; 22 nC QG ensures minimal gate drive loss at 65 kHz switching frequency. |
Use Scenario: Standby auxiliary supply (12 V/100 mA) for smart meter main board, operating continuously during meter sleep mode. IC Role / Device Role / Timing Role: Self-oscillating flyback switch in low-cost, low-component-count auxiliary supply (e.g., using TNY274 secondary-side feedback). Use Value: Low IDSS (100 μA max) minimizes no-load input power; TO-263 package allows direct thermal coupling to chassis for long-term reliability at 70°C ambient. |
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, 0.75 Ω RDS(on), 25 nC QG, TO-220FP package | Higher conduction efficiency but slower switching (tr = 25 ns vs. 11 ns); no integrated avalanche rating published | Preferred for lower-loss, lower-frequency (<100 kHz) applications where thermal mass of TO-220FP suffices. |
| IXTP50N10P | 100 V, 0.022 Ω RDS(on), 42 nC QG, TO-220 package | Lower voltage rating prohibits direct replacement; higher QG increases gate drive demand | Only suitable in low-voltage secondary-side synchronous rectifier or DC-DC stage - not a functional substitute for primary-side 600 V switching. |
Compared with STP6NK60ZFP and IXTP50N10P, the 2SK3116B-ZK-E1-AY offers superior avalanche ruggedness and faster switching at 600 V, making it uniquely suited for compact, high-reliability offline flyback designs where transient immunity and layout-constrained thermal performance are critical.

FAQ
What is the maximum continuous drain current rating for the 2SK3116B-ZK-E1-AY?
The 2SK3116B-ZK-E1-AY has a DC drain current rating of ±7.5 A at TA = 25°C. However, practical continuous current is limited by thermal design: with proper PCB copper pour on the TO-263 drain tab, sustained operation up to 4.5 A is achievable at 70°C ambient. Always verify junction temperature using Rth(ch-A) = 83.3°C/W and actual power dissipation in the 2SK3116B-ZK-E1-AY's application.
Does the 2SK3116B-ZK-E1-AY have a specified avalanche energy rating?
Yes, the 2SK3116B-ZK-E1-AY is fully rated for unclamped inductive switching with a single-pulse avalanche energy (EAS) of 37.5 mJ at VDD = 150 V, starting Tch = 25°C, and RG = 25 Ω. This specification is measured and guaranteed per JEDEC JESD24-11, confirming ruggedness for flyback transformer leakage spike absorption without external snubbers in the 2SK3116B-ZK-E1-AY's intended use cases.
What is the gate threshold voltage range for the 2SK3116B-ZK-E1-AY?
The 2SK3116B-ZK-E1-AY has a gate threshold voltage (VGS(off)) range of 2.5 V to 3.5 V, defined at VDS = 10 V and ID = 1 mA. This ensures reliable turn-on with standard 5 V logic-level drivers and compatibility with PWM controllers such as UC3842 or TL494, while maintaining noise immunity against spurious gate triggering in the 2SK3116B-ZK-E1-AY's high-noise power stage environment.
Can the 2SK3116B-ZK-E1-AY be used in synchronous rectification applications?
No - the 2SK3116B-ZK-E1-AY is optimized as a primary-side high-voltage switch, not a low-side synchronous rectifier. Its body diode forward voltage (0.93 V at 7.5 A) and reverse recovery time (390 ns) are significantly higher than dedicated SR MOSFETs. For secondary-side synchronous rectification, use devices like IRF7832 or SiR872DP, not the 2SK3116B-ZK-E1-AY.
What is the thermal resistance from channel to ambient for the 2SK3116B-ZK-E1-AY?
The 2SK3116B-ZK-E1-AY has a transient thermal resistance Rth(ch-A) of 83.3°C/W for a 10 ms pulse, per the datasheet's transient thermal impedance curve. For steady-state operation, effective Rth(ch-A) depends entirely on PCB layout: with 4 cm² of 2 oz copper connected to the TO-263 drain tab, typical values range from 40–60°C/W. Always calculate worst-case Tj using actual power and measured thermal resistance in the final 2SK3116B-ZK-E1-AY layout.
