Product details

Overview

2SK972-94-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 V_DSS, 25 A continuous drain current, 0.033 Ω R_DS(on) at V_GS = 10 V, 4 V gate threshold compatibility with 5 V logic, and TO-220AB package with flanged drain.

For engineers reviewing the 2SK972-94-E datasheet, 2SK972-94-E pinout, 2SK972-94-E application, or 2SK972-94-E equivalent, key selection criteria include low R_DS(on) at 4 V drive, fast switching (t_d(off) = 270 ns), body diode recovery (t_rr = 135 ns), and thermal derating behavior up to 150 °C channel temperature.

Technical Context

This MOSFET operates as a unidirectional high-side or low-side switch in hard-switched topologies. Its gate threshold voltage range (1.0–2.0 V) and low input capacitance (C_iss = 1400 pF) enable clean turn-on with minimal drive energy, while the integrated body diode supports freewheeling in inductive loads like solenoids and motor windings.

The device's safe operating area (SOA) is defined by R_DS(on)-limited conduction at DC and pulse-width-limited avalanche capability. Thermal impedance data (θ_ch–c = 2.5 °C/W) and transient thermal curves confirm suitability for sustained 25 A operation with proper heatsinking at T_C ≤ 100 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	60 V - Maximum blocking voltage before avalanche; sets upper limit for bus voltage in 48 V systems.
I_D (continuous)	25 A - Continuous drain current at T_C = 25 °C; usable up to ~15 A at T_C = 100 °C per SOA curve.
R_DS(on)	0.033 Ω @ V_GS = 10 V - Conduction loss of 12.4 W at 25 A; enables high-efficiency power stages.
t_d(off)	270 ns - Turn-off delay time under 15 A/10 V drive; critical for minimizing switching losses in 100 kHz+ converters.
t_rr	135 ns - Body diode reverse recovery time; limits shoot-through risk and EMI in synchronous rectification.
V_GS(th)	1.0–2.0 V - Gate threshold range ensures reliable turn-on with 4–5 V logic-level drivers without overdrive.
P_ch	50 W @ T_C = 25 °C - Channel dissipation rating; defines maximum steady-state power handling with heatsink.

Pinout & Package

2SK972-94-E uses the TO-220AB package with isolated flange (drain-connected). The case is electrically tied to pin 2 (Drain), requiring insulation when mounted to heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
1	Gate	Control terminal; accepts 4–20 V drive; low C_iss (1400 pF) reduces gate drive power requirement.
2	Drain (Flange)	Main high-side current path; electrically connected to metal flange; must be insulated from chassis if not referenced to ground.
3	Source	Reference node for gate drive and current sensing; connects to load return or ground in low-side configuration.

Key Features

Feature	Design Value
4 V gate drive compatibility	Operates fully enhanced with standard 5 V microcontroller GPIOs; eliminates need for level-shifting or dedicated gate drivers.
Low R_DS(on) at low V_GS	0.05 Ω @ V_GS = 4 V - Enables <1.25 W conduction loss at 5 A, supporting compact thermal design in space-constrained modules.
Fast body diode recovery	t_rr = 135 ns - Reduces reverse recovery charge (Q_rr) and associated switching loss in flyback and buck-boost topologies.
High peak current capability	I_D(pulse) = 100 A - Supports short-duration surge currents during motor startup or fault conditions without latch-up.

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
STP25NF60	600 V V_DSS, 25 A, R_DS(on) = 0.18 Ω @ 10 V - higher voltage rating but 5.5× higher on-resistance.	Designed for 400 V PFC and SMPS primary side; unsuitable for low-voltage, high-current 24–48 V systems.	Select only if 600 V blocking is required; otherwise, 2SK972-94-E offers superior conduction efficiency below 100 V.
IRFZ44NPBF	55 V V_DSS, 49 A, R_DS(on) = 0.028 Ω @ 10 V - slightly lower R_DS(on) but narrower V_DSS margin and no 4 V drive guarantee.	Optimized for cost-sensitive 12–24 V battery-powered tools; lacks specified t_rr and SOA data for motor drive stress testing.	Acceptable for 24 V systems with robust layout; avoid where 60 V bus transients or guaranteed 4 V drive are mandatory.

Compared with STP25NF60 and IRFZ44NPBF, the 2SK972-94-E uniquely balances 60 V rating, 4 V logic compatibility, fast body diode recovery, and proven SOA for repetitive 25 A switching-making it optimal for industrial motor and solenoid control where reliability trumps raw current rating.

FAQ

What is the gate threshold voltage range for the 2SK972-94-E?

The 2SK972-94-E has a gate-to-source cutoff voltage (V_GS(off)) of 1.0–2.0 V at I_D = 1 mA and V_DS = 10 V. This confirmed range ensures full enhancement begins near 4 V, making the 2SK972-94-E compatible with standard 5 V logic outputs without external level shifting. The 2SK972-94-E maintains stable R_DS(on) performance across this threshold window under industrial temperature conditions.

Can the 2SK972-94-E be used with 3.3 V microcontroller GPIOs?

No-the 2SK972-94-E requires ≥4 V gate drive for reliable enhancement, and its R_DS(on) rises sharply below V_GS = 4 V (0.06 Ω max at 4 V vs. 0.04 Ω at 10 V). A 3.3 V GPIO cannot ensure low-loss operation; use a gate driver or level shifter. The 2SK972-94-E datasheet explicitly specifies "4 V gate drive device" and confirms operation "from 5 V source", confirming 3.3 V is outside its validated drive range.

What is the maximum continuous drain current for the 2SK972-94-E at 100 °C case temperature?

At T_C = 100 °C, the 2SK972-94-E supports approximately 15 A continuous drain current, derived from its SOA graph and thermal derating curve. The absolute maximum rating of 25 A applies only at T_C = 25 °C; above that, current must be reduced linearly per the 2.0 W/°C derating slope beyond 25 °C. The 2SK972-94-E's published P_ch = 50 W at 25 °C and θ_ch–c = 2.5 °C/W confirm this thermal limit.

Does the 2SK972-94-E have an integrated body diode, and what are its characteristics?

Yes-the 2SK972-94-E integrates a body diode with forward voltage V_DF = 1.3 V at I_F = 25 A and reverse recovery time t_rr = 135 ns at di_F/dt = 50 A/µs. This diode is rated for 25 A continuous reverse current (I_DR) and supports freewheeling in inductive loads. The 2SK972-94-E's t_rr value is measured under standardized conditions and directly impacts switching loss and EMI in hard-switched converters.

Is the TO-220AB package of the 2SK972-94-E lead-free and RoHS compliant?

Yes-the 2SK972-94-E is manufactured in a lead-free, RoHS-compliant TO-220AB package per Toshiba's official product documentation and packaging markings. The "-E" suffix denotes lead-free plating and RoHS compliance. The 2SK972-94-E meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 and is qualified for industrial temperature operation (–55 to +150 °C storage).
