Product details

Overview

2SK974-93L-E from Toshiba is a silicon N-channel MOSFET designed for high-speed power switching in DC-DC converters and motor drive circuits, featuring 60 V V_DSS, 3 A continuous drain current, 0.15 Ω R_DS(on) at V_GS = 10 V, and 4 V gate threshold compatibility with 5 V logic-level drive.

For engineers reviewing the 2SK974-93L-E datasheet, 2SK974-93L-E pinout, 2SK974-93L-E application, or 2SK974-93L-E equivalent, key selection criteria include low R_DS(on) at 4 V gate drive, fast switching (t_d(off) = 180 ns), body diode recovery time (t_rr = 85 ns), and DPAK-1 package thermal performance for industrial solenoid and power switch designs.

Technical Context

This device operates as a single N-channel enhancement-mode MOSFET with gate-controlled conduction, optimized for unidirectional high-efficiency power switching where low gate charge and fast turn-off are critical. Its 4 V gate threshold enables direct interface with 5 V microcontrollers without level-shifting circuitry.

The integrated body diode supports freewheeling in inductive loads, with t_rr = 85 ns and V_DF = 0.9 V at I_F = 3 A, making it suitable for synchronous rectification and flyback topologies requiring controlled reverse recovery behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum blocking voltage before avalanche breakdown; sets upper limit for DC-DC input or motor supply rails.
R_DS(on) @ V_GS = 4 V	0.20–0.25 Ω - Enables efficient 5 V logic-driven switching with minimal conduction loss at 2 A load.
t_d(off)	180 ns - Fast turn-off delay supports >500 kHz switching frequencies in hard-switched converters.
t_rr	85 ns - Low reverse recovery time reduces switching losses and EMI in inductive load commutation.
P_ch @ T_C = 25°C	20 W - Thermal limit at case temperature defines heatsink sizing for continuous 3 A operation.
V_GS(off)	1.0–2.0 V - Precise gate threshold ensures reliable turn-on margin above noise while minimizing shoot-through risk.
C_iss	400 pF - Input capacitance determines required gate drive strength and influences switching speed vs. gate resistance trade-offs.

Pinout & Package

2SK974-93L-E uses the DPAK-1 (TO-252AA) surface-mount package with exposed drain pad for enhanced thermal dissipation. 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; accepts 4–10 V logic-level signals to modulate channel conductivity.
2 (D)	Drain	Main high-side power terminal; electrically tied to Pin 4 and thermally connected to exposed pad.
3 (S)	Source	Power return path and reference node for gate drive; connects to ground or low-side switch node.
4 (D)	Drain	Second drain connection; paralleled with Pin 2 to reduce package inductance and improve current sharing.

Key Features

Feature	Design Value
Logic-level gate drive	Operates fully enhanced at V_GS = 4 V, enabling direct interface with 5 V MCU GPIOs without external level shifters.
Low R_DS(on) at low V_GS	0.25 Ω max at V_GS = 4 V and I_D = 2 A - minimizes conduction loss in battery-powered or low-voltage systems.
Fast body diode recovery	t_rr = 85 ns - reduces switching loss and voltage spikes during inductive flyback in motor and solenoid drivers.
Dual-drain thermal design	Pins 2 and 4 both connect to drain and exposed pad - lowers thermal resistance (θ_ch–c = 6.25°C/W) for sustained 3 A operation.

FAQ

What is the maximum continuous drain current for the 2SK974-93L-E?

The 2SK974-93L-E supports a continuous drain current of 3 A at T_C = 25°C. Derating applies above this temperature-e.g., ~1.5 A at T_C = 100°C per the power vs. temperature curve. This rating assumes proper PCB copper area and thermal vias under the exposed drain pad to maintain case temperature within limits.

Can the 2SK974-93L-E be driven directly by a 5 V microcontroller?

Yes, the 2SK974-93L-E is explicitly specified as a 4 V gate drive device and achieves full enhancement at V_GS = 5 V, with R_DS(on) = 0.20–0.25 Ω at I_D = 2 A. No external level shifter or gate driver is needed, simplifying interface design for 5 V logic systems.

What is the body diode forward voltage of the 2SK974-93L-E?

The body diode forward voltage (V_DF) of the 2SK974-93L-E is 0.9 V typical at I_F = 3 A and V_GS = 0. This value is measured under pulsed conditions and reflects low conduction loss during freewheeling in inductive switching applications like motor drives.

Does the 2SK974-93L-E have a dual-drain configuration?

Yes, the 2SK974-93L-E features a dual-drain configuration: Pins 2 and 4 are both internally connected to the drain and to the exposed thermal pad. This design reduces package inductance and improves thermal transfer, supporting higher peak current (12 A) and stable 3 A continuous operation.

What is the gate-to-source cutoff voltage range for the 2SK974-93L-E?

The gate-to-source cutoff voltage (V_GS(off)) for the 2SK974-93L-E is specified as 1.0–2.0 V at I_D = 1 mA and V_DS = 10 V. This narrow threshold range ensures predictable turn-on behavior and immunity to false triggering from noise in industrial environments.
