Product details
Overview
2SK3740-ZK-E1-AY from Renesas Electronics is an N-channel power MOSFET designed for high-voltage switching applications, featuring RDS(on) = 160 mΩ max at VGS = 10 V and ID = 10 A, VDSS = 250 V, and TO-263 (MP-25ZK) surface-mount package. It delivers low gate charge (QG = 47 nC typ.) and robust avalanche capability (EAS = 40 mJ), enabling use in DC/DC converters and lamp drivers.
For engineers reviewing the 2SK3740-ZK-E1-AY datasheet, 2SK3740-ZK-E1-AY pinout, 2SK3740-ZK-E1-AY application, or 2SK3740-ZK-E1-AY equivalent, this device is evaluated for high-efficiency, medium-power switching where thermal performance (Rth(ch–C) = 1.25 °C/W), fast turn-off (td(off) = 49 ns), and body diode recovery (trr = 210 ns) are critical selection criteria.
Technical Context
This MOSFET employs a planar vertical DMOS structure optimized for high-voltage blocking and low conduction loss. Its gate threshold voltage (VGS(off) = 2.5–4.5 V) ensures reliable enhancement-mode operation, while the integrated gate-source ESD protection diode supports handling robustness without compromising switching speed.
The device's capacitance profile (Ciss = 1720 pF, Coss = 330 pF, Crss = 170 pF at VDS = 10 V) enables predictable Miller-effect behavior in hard-switched topologies. Avalanche-rated design allows single-pulse energy absorption up to 40 mJ under defined test conditions (VDD = 125 V, L = 100 µH, RG = 25 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 250 V - Supports primary-side switching in offline 200 VAC-derived supplies and industrial 24–48 V bus systems with margin. |
| RDS(on) max | 160 mΩ at VGS = 10 V, ID = 10 A - Enables ≤1.6 W conduction loss at 10 A DC, suitable for continuous 15–20 A pulsed loads. |
| QG | 47 nC typ. at VDD = 200 V - Reduces gate drive power and enables efficient operation with standard 1–2 A peak gate drivers. |
| td(off) | 49 ns with RG = 0 Ω - Supports >1 MHz switching in resonant or ZVS circuits when combined with low Crss. |
| EAS | 40 mJ single-pulse - Allows unclamped inductive switching in relay drivers or solenoid controls without external snubbers. |
| Tch max | 150 °C - Permits operation in sealed enclosures or high-ambient environments when heatsinked per Rth(ch–C) = 1.25 °C/W. |
| ID(pulse) | ±60 A (PW ≤ 10 µs, duty ≤ 1%) - Supports high-current transient loads such as motor startup or capacitor charging. |
Pinout & Package
2SK3740-ZK-E1-AY is housed in a TO-263 (MP-25ZK) surface-mount package with exposed drain tab for thermal and electrical connection. The 4-pin configuration integrates drain (pins 2 & 4), source (pin 3), and gate (pin 1); pin 4 is the metal fin directly connected to drain.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives voltage-controlled signal to modulate channel conductivity; requires ≤±30 V rating and low-impedance drive due to 47 nC QG. |
| 2 (Drain) | High-side power input | Connected to high-voltage rail (up to 250 V); electrically and thermally tied to metal fin (pin 4) for PCB heat spreading. |
| 3 (Source) | Power return/reference | Serves as current return path and gate drive reference; must be routed with low inductance to minimize switching oscillation. |
| 4 (Fin / Drain) | Thermal & power node | Exposed copper tab soldered to large PCB copper area; provides primary thermal path (Rth(ch–C) = 1.25 °C/W) and secondary drain connection. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) with high VDSS | 160 mΩ @ 250 V enables higher efficiency than comparable 200 V MOSFETs in 24–48 V industrial power stages. |
| Fast, low-QG switching | 47 nC total gate charge and 49 ns td(off) reduce driver losses and enable compact magnetics in SMPS designs. |
| Integrated gate ESD protection | On-chip gate-source diode limits transient overvoltage during handling and board assembly-no external Zener required. |
| Avalanche-rated operation | Guaranteed 40 mJ single-pulse energy absorption allows safe unclamped inductive turn-off in actuator and lamp drivers. |
| TO-263 thermal performance | 1.25 °C/W channel-to-case resistance supports ≥80 W continuous dissipation with minimal heatsink on 2 oz. copper. |
Applications
| Lamp Driver | DC/DC Converter |
|---|---|
|

IC Role / Device Role / Timing Role: Main high-side switching element in buck-derived constant-current driver topology. Use Value: Low RDS(on) minimizes thermal derating at full load; avalanche rating absorbs lamp ignition surge without snubber. |
Use Scenario: Primary-side switch in isolated flyback or forward converter for industrial 24 V output from 300 V DC bus. IC Role / Device Role / Timing Role: Power switch operating at 100–500 kHz with synchronous rectification on secondary side. Use Value: Fast td(off) and low Crss reduce cross-conduction loss; TO-263 package enables direct heatsinking to chassis ground. |
| Actuator Driver | Motor Starter Circuit |
|
Use Scenario: Solenoid or linear actuator control in factory automation systems with 24–48 V supply and inductive loads up to 20 A. IC Role / Device Role / Timing Role: Low-side or high-side switch managing inductive energy recirculation via body diode or external freewheeling path. Use Value: Body diode VF(S-D) = 0.91 V at 20 A reduces conduction loss during flyback; trr = 210 ns limits reverse recovery overshoot. |
Use Scenario: Soft-start or pre-charge switch in BLDC motor inverters or HVAC compressor drives. IC Role / Device Role / Timing Role: Inrush current limiter bypassed after capacitor bank charging completes. Use Value: 60 A pulse rating handles 5× stall current surges; Rth(ch–C) = 1.25 °C/W prevents thermal runaway during repeated start cycles. |
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 |
|---|---|---|---|
| STP20NM50FP | VDSS = 500 V, RDS(on) = 240 mΩ, D2PAK package, no specified EAS rating | Better voltage margin but higher conduction loss; lacks documented avalanche capability | Select when system requires >250 V headroom and can accept 50% higher RDS(on); verify layout compatibility with D2PAK footprint. |
| IXTP20N50D2 | VDSS = 500 V, RDS(on) = 220 mΩ, TO-220 package, Rth(ch–C) = 1.0 °C/W | Higher voltage rating and slightly better thermal resistance, but through-hole mounting only | Prefer for prototyping or low-volume assemblies where TO-220 mechanical stability outweighs SMT assembly benefits. |

FAQ
What is the maximum continuous drain current rating for the 2SK3740-ZK-E1-AY?
The 2SK3740-ZK-E1-AY has a DC drain current rating of ±20 A at TC = 25°C. This value is thermally limited-actual usable current depends on PCB copper area, heatsinking, and ambient temperature. At TC = 100°C, derating reduces the practical continuous current to approximately 12 A based on the 1.25 °C/W channel-to-case thermal resistance and 150 °C maximum channel temperature.
Does the 2SK3740-ZK-E1-AY include built-in gate protection?
Yes, the 2SK3740-ZK-E1-AY integrates a gate-source protection diode to suppress electrostatic discharge (ESD) events during handling and assembly. This diode clamps gate voltage to within ±30 V, matching the device's absolute maximum gate rating. However, external gate resistors and TVS protection remain recommended in high-noise industrial environments where transients may exceed the diode's energy handling capacity.
Can the 2SK3740-ZK-E1-AY be used in avalanche mode repeatedly?
No-the 2SK3740-ZK-E1-AY is rated for single-pulse avalanche only (EAS = 40 mJ, IAS = 20 A). Repeated avalanche operation is not characterized or guaranteed and may cause parametric shift or premature failure. Designers must ensure circuit conditions (e.g., inductive energy, VDD, gate timing) stay within single-pulse test conditions or implement clamping to avoid entering avalanche during normal operation.
What is the typical reverse recovery time of the body diode in the 2SK3740-ZK-E1-AY?
The body diode reverse recovery time (trr) of the 2SK3740-ZK-E1-AY is 210 ns under test conditions of IF = 20 A, VGS = 0 V, and di/dt = 100 A/µs. This value reflects moderate-speed recovery suitable for non-synchronous rectification in <500 kHz converters but not recommended for high-frequency synchronous FET replacement without external Schottky assist.
Is the 2SK3740-ZK-E1-AY RoHS compliant?
Yes, the 2SK3740-ZK-E1-AY is RoHS compliant per EU Directive 2011/65/EU. Renesas Electronics confirms lead-free plating and halogen-free molding compound for this part number, consistent with its "Standard" quality grade classification and intended use in office equipment, industrial robots, and communications gear.
