Product details
Overview
2SK3740-ZK-E1-AZ 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 robust avalanche capability (EAS = 40 mJ), low gate charge (QG = 47 nC typ.), and fast switching (td(off) = 49 ns), making it suitable for DC/DC converters and lamp drivers.
For engineers reviewing the 2SK3740-ZK-E1-AZ datasheet, 2SK3740-ZK-E1-AZ pinout, 2SK3740-ZK-E1-AZ application, or 2SK3740-ZK-E1-AZ equivalent, this page provides verified electrical parameters, thermal derating behavior, body diode recovery characteristics (trr = 210 ns), safe operating area limits, and validated alternative parts for industrial power switching designs.
Technical Context
This device 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 turn-on with standard logic-level gate drivers, while its 1.25 °C/W channel-to-case thermal resistance supports high-power operation when mounted on thermally enhanced PCBs.
The integrated body diode exhibits VF(S-D) = 0.91 V at IF = 20 A and trr = 210 ns under specified conditions, enabling use in synchronous rectification and freewheeling paths. Avalanche ruggedness is confirmed per test circuit with L = 100 µH, VDD = 125 V, and RG = 25 Ω.

Pinout & Package
2SK3740-ZK-E1-AZ is housed in a TO-263 (MP-25ZK) surface-mount package with exposed drain tab (Pin 4) for thermal and electrical connection. The package features 4 terminals: Gate (Pin 1), Drain (Pin 2), Source (Pin 3), and Fin/Drain (Pin 4). Pin 4 is electrically and thermally tied to Pin 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control electrode | Receives gate drive signal; ±30 V rating allows compatibility with standard isolated gate drivers. |
| 2 (Drain) | High-side current path input | Connects to high-voltage rail; shares thermal path with Pin 4 for enhanced heat dissipation. |
| 3 (Source) | Reference node for gate drive | Serves as return path for load current and gate drive reference; must be routed with low inductance. |
| 4 (Fin/Drain) | Thermal and electrical drain extension | Large copper tab for soldering to PCB thermal pad; reduces Rth(ch-A) to 83.3 °C/W when properly mounted. |
Key Features

IC Role / Device Role / Timing Role: Low-side or high-side switch enabling precise pulse-width modulated actuation. Use Value: Confirmed single-avalanche rating absorbs inductive energy without clamping diodes; VF(S-D) = 0.91 V reduces freewheeling loss. |
Use Scenario: 24–48 V brushed DC motor H-bridge where one leg uses N-channel high-side configuration. IC Role / Device Role / Timing Role: High-side switch in half-bridge topology, driven by bootstrap or isolated gate driver. Use Value: VGS(off) range ensures stable turn-on with 10 V gate drive; low QG enables clean gate waveform even with limited driver current. |
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, TO-220FP package, no integrated gate protection diode. | Higher voltage rating but higher RDS(on); requires external gate protection; unsuitable for space-constrained SMT layouts. | Select when 500 V blocking is mandatory and thermal budget allows higher conduction loss. |
| IXTP20N50P | VDSS = 500 V, RDS(on) = 220 mΩ, TO-220 package, lower QG (38 nC), no avalanche rating specified. | Superior switching speed but lacks documented EAS; not qualified for repetitive inductive switching without external clamping. | Prefer for high-frequency ZVS/ZCS topologies where avalanche stress is absent and layout permits through-hole mounting. |
Compared with STP20NM50FP and IXTP20N50P, the 2SK3740-ZK-E1-AZ offers optimal balance of 250 V rating, low RDS(on), proven avalanche ruggedness, and SMT-ready TO-263 packaging-making it uniquely suited for cost-sensitive, thermally constrained industrial switching where reliability under transient overload is critical.

FAQ
What is the maximum continuous drain current rating for the 2SK3740-ZK-E1-AZ at 25°C case temperature?
The 2SK3740-ZK-E1-AZ has a DC drain current rating of ±20 A at TC = 25°C, as specified in its Absolute Maximum Ratings table. This value assumes ideal heatsinking; actual usable current must be derated per the Total Power Dissipation vs. Case Temperature curve, especially above 25°C. For sustained 20 A operation, thermal design must maintain TC ≤ 25°C using the TO-263's exposed drain tab.
Does the 2SK3740-ZK-E1-AZ include built-in gate protection?
Yes, the 2SK3740-ZK-E1-AZ integrates a gate-to-source protection diode to guard against electrostatic discharge (ESD) during handling and assembly. However, the datasheet explicitly states that an external protection circuit remains necessary if voltages exceeding the ±30 V gate rating may occur in the final application-such as from Miller-induced spikes or gate driver faults.
What is the typical reverse recovery time (trr) of the body diode in the 2SK3740-ZK-E1-AZ?
The body diode of the 2SK3740-ZK-E1-AZ has a reverse recovery time (trr) of 210 ns under test conditions of IF = 20 A, VGS = 0 V, and di/dt = 100 A/µs. This parameter is critical for freewheeling performance in buck or half-bridge configurations, and its consistency across temperature is confirmed in the Typical Characteristics section.
Can the 2SK3740-ZK-E1-AZ be used in avalanche-mode operation?
Yes-the 2SK3740-ZK-E1-AZ is rated for single-pulse avalanche operation with IAS = 20 A and EAS = 40 mJ under defined conditions (VDD = 125 V, L = 100 µH, RG = 25 Ω, starting Tch = 25°C). It is not rated for repetitive avalanche; repeated exposure beyond single-pulse limits risks parametric shift or catastrophic failure.
What is the gate threshold voltage range for the 2SK3740-ZK-E1-AZ?
The gate threshold voltage (VGS(off)) of the 2SK3740-ZK-E1-AZ is specified as 2.5 V (min) to 4.5 V (max) at VDS = 10 V and ID = 1.0 mA. This range ensures consistent turn-on behavior with 5 V or 10 V gate drive, and its variation with channel temperature is documented in the Typical Characteristics curves.
