Product details
Overview
2SK974L-E from Toshiba is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drive circuits. It features 60 V VDSS, 3 A continuous drain current, 0.15 Ω RDS(on) at VGS = 10 V, 4 V gate threshold compatibility with 5 V logic, and 180 ns turn-off delay time.
For engineers reviewing the 2SK974L-E datasheet, 2SK974L-E pinout, 2SK974L-E application, or 2SK974L-E equivalent, this device supports low-drive-current, high-efficiency power switching where fast transition times and low conduction loss are critical in compact industrial and automotive power stages.
Technical Context
This MOSFET employs a planar vertical DMOS structure optimized for low RDS(on) and fast switching. Its gate threshold voltage (VGS(off) = 1.0–2.0 V) enables reliable enhancement-mode operation with TTL/CMOS-compatible 4–5 V drive, while its body diode exhibits 85 ns reverse recovery time and 0.9 V forward voltage at 3 A.
The device operates within a channel temperature range of –55°C to +150°C and delivers 20 W channel dissipation at TC = 25°C. Its safe operating area (SOA) is defined up to 100 V and 3 A under pulsed conditions (PW ≤ 10 µs), limited by RDS(on) at higher voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche; suitable for 48 V bus and 36 V automotive systems |
| RDS(on) @ VGS = 4 V | 0.20–0.25 Ω - Enables direct 5 V microcontroller drive without level-shifting in solenoid or low-power motor control |
| td(off) | 180 ns - Supports >500 kHz switching in synchronous buck converters with minimal dead-time overhead |
| ID (continuous) | 3 A - Sustains steady-state load current in fan drivers, LED backlighting, and small DC-DC modules |
| Ciss | 400 pF - Low input capacitance reduces gate drive power and improves EMI performance in high-frequency SMPS |
| VGS(off) | 1.0–2.0 V - Ensures robust turn-off margin against noise and guarantees zero conduction when gate is grounded |
| trr | 85 ns - Limits reverse recovery losses during hard-switched freewheeling in half-bridge topologies |
Pinout & Package
2SK974L-E uses the DPAK-1 (TO-252-3) surface-mount package with exposed drain pad for thermal enhancement. Pin 1 = Gate, Pin 2 = Drain, Pin 3 = Source, Pin 4 = Drain (dual-drain configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control terminal requiring ≤±10 µA leakage; driven directly from 5 V MCU GPIO or dedicated gate driver |
| 2 & 4 (D) | Drain | High-side switching node; electrically tied together and thermally connected to exposed copper pad for PCB heat sinking |
| 3 (S) | Source | Power return path and reference for gate drive; connects to ground or low-side switch source in half-bridge |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4 V drive | 0.20–0.25 Ω - Reduces conduction loss by >30% vs. standard 10 V-gate MOSFETs in 5 V logic-controlled applications |
| Fast switching speed | 5 ns td(on), 25 ns tr, 180 ns td(off), 75 ns tf - Minimizes transition losses in high-frequency DC-DC converters |

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 |
|---|---|---|---|
| STP3NK60ZFP | 600 V VDSS, 2.5 A ID, 3.3 Ω RDS(on) @ 10 V - higher voltage rating but significantly higher on-resistance | Designed for offline SMPS primary side; unsuitable for 48 V bus due to excessive conduction loss | Select only if 600 V blocking is required; not interchangeable for low-voltage switching |
| IRLML6344TRPBF | 20 V VDSS, 4.3 A ID, 0.045 Ω RDS(on) @ 4.5 V - lower voltage, much lower RDS(on), SOT-23 package | Optimized for battery-powered portable electronics; insufficient VDSS for 36 V+ systems | Use only in ≤20 V applications where space and ultra-low RDS(on) outweigh voltage margin needs |
Compared with STP3NK60ZFP and IRLML6344TRPBF, the 2SK974L-E uniquely balances 60 V rating, 4 V gate drive capability, and sub-0.25 Ω on-resistance in DPAK - making it optimal for mid-voltage industrial motor and converter designs where both voltage headroom and logic-level drive are essential.

FAQ
What is the maximum continuous drain current for the 2SK974L-E?
The 2SK974L-E has a maximum continuous drain current (ID) of 3 A at TC = 25°C. This rating assumes proper PCB thermal management via the DPAK-1 exposed drain pad. At elevated case temperatures, derating applies per the power vs. temperature curve - e.g., ~1.5 A at TC = 100°C. The 12 A peak current rating applies only for PW ≤ 10 µs and duty cycle ≤ 1%.
Can the 2SK974L-E be driven directly from a 5 V microcontroller GPIO?
Yes, the 2SK974L-E is explicitly characterized as a "4 V gate drive device" and supports full enhancement at VGS = 4–5 V. Its RDS(on) is specified at 0.20–0.25 Ω under VGS = 4 V, confirming reliable on-state operation without external level shifting. Gate leakage remains ≤±10 µA at ±16 V, ensuring low drive current demand.
What is the body diode reverse recovery time of the 2SK974L-E?
The 2SK974L-E body diode has a reverse recovery time (trr) of 85 ns under test conditions of IF = 3 A, VGS = 0, and diF/dt = 50 A/µs. This value is measured and guaranteed per Toshiba's characterization, enabling predictable freewheeling behavior in non-synchronous buck or flyback converters without requiring an external Schottky diode.
Does the 2SK974L-E have a dual-drain pin configuration?
Yes, the 2SK974L-E in DPAK-1 (TO-252-3) package features pins 2 and 4 both connected to the drain terminal. This dual-drain layout improves current handling and thermal spreading across the PCB copper area. Pin 1 is gate, pin 3 is source, and pins 2/4 are internally shorted drain terminals - confirmed in Toshiba's official pin diagram and package outline.
What is the gate-to-source cutoff voltage range for the 2SK974L-E?
The gate-to-source cutoff voltage (VGS(off)) for the 2SK974L-E is specified as 1.0–2.0 V at ID = 1 mA and VDS = 10 V. This defines the threshold region where the device transitions from off to on. The narrow range ensures consistent turn-on behavior across units and simplifies gate drive design for deterministic switching in timing-critical applications.
