Product details

Overview

PSMN2R2-40PS from Nexperia is a standard-level N-channel MOSFET in TO-220AB (SOT78) package, rated for 40 V V_DS, 2.1 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and qualified to 175 °C junction temperature. It delivers 100 A continuous drain current at T_mb = 25 °C and supports high-efficiency power switching in industrial DC-DC converters and server power supplies.

For engineers reviewing the PSMN2R2-40PS datasheet, PSMN2R2-40PS pinout, PSMN2R2-40PS application, or PSMN2R2-40PS equivalent, key selection criteria include its low conduction loss (1.75–2.1 mΩ), robust avalanche energy rating (1.24 J), gate-threshold voltage range (2–4 V), and thermal resistance from junction to mounting base (0.25–0.5 K/W).

Technical Context

This MOSFET employs a planar silicon process optimized for standard-level gate drive compatibility (V_GS = 10 V), enabling direct use with legacy 10 V logic or driver ICs without level-shifting. Its R_DS(on) remains stable across -55 °C to 175 °C, supported by a normalized on-resistance factor of ~1.0 at 25 °C and ~1.3 at 175 °C.

The device features a fast-switching profile: Q_G(tot) = 110–130 nC, Q_GD = 25 nC, and t_d(off)/t_f = 66.6 ns / 25.2 ns under 1.5 Ω external gate resistance. Its source-drain diode exhibits V_SD = 0.85–1.2 V at I_S = 25 A and T_j = 25 °C, with t_rr = 53.7 ns and Q_r = 80.75 nC under specified conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	40 V - Maximum drain-source blocking voltage; defines safe operating ceiling in buck, half-bridge, or load-switch topologies.
R_DS(on)	1.75–2.1 mΩ @ V_GS = 10 V, I_D = 25 A, T_j = 25 °C - Enables <1.5 W conduction loss at 60 A, critical for high-current server PSU rails.
I_D (cont)	100 A @ T_mb = 25 °C - Sustains full-load current in high-power motor drives when heatsinked to ambient.
E_AS	1.24 J - Non-repetitive avalanche energy rating; allows reliable operation during inductive turn-off transients without snubbers.
R_th(j-mb)	0.25–0.5 K/W - Low thermal resistance enables >250 W dissipation with modest heatsinking, supporting compact thermal design.
V_GS(th)	2–4 V - Gate threshold ensures clean turn-on with 5 V or 10 V logic; avoids partial-conduction risk in noisy environments.
Q_G(tot)	110–130 nC - Total gate charge determines driver strength requirement; compatible with common 1–2 A peak gate drivers.

Pinout & Package

PSMN2R2-40PS uses the TO-220AB (SOT78) plastic single-ended package with heatsink-mounted base and one mounting hole. The metal tab (pin 2) is electrically connected to the drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control input; requires ≤20 V absolute max; 10 V nominal for full enhancement; internal R_G = 1 Ω limits ringing.
2 (D) / mb	Drain / Mounting Base	Main power output node; electrically tied to heatsink; carries full load current and must be isolated if heatsink is grounded.
3 (S)	Source	Power return path and reference for gate drive; connects to low-side switch node or ground plane in high-side configurations.

Key Features

Feature	Design Value
High-temperature qualification	Rated for continuous operation up to 175 °C junction temperature-enables deployment in sealed industrial enclosures without derating.
Low R_DS(on) drift over temperature	R_DS(on) increases only ~30% from 25 °C to 175 °C-maintains efficiency in thermally constrained systems.
Standard-level gate drive	Optimized for 10 V gate drive-eliminates need for gate boosters or level shifters in legacy 5/10 V control architectures.
Avalanche ruggedness	1.24 J unclamped inductive switching energy-reduces reliance on external clamping components in motor or relay drive circuits.
Fast body diode recovery	t_rr = 53.7 ns, Q_r = 80.75 nC-minimizes reverse recovery losses in synchronous rectification and freewheeling paths.

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
IRF1404PBF	R_DS(on) = 4.7 mΩ @ 10 V; V_DS = 40 V; TO-220; Q_G = 131 nC	Higher conduction loss (~2.2×), lower thermal performance (R_th(j-mb) ≈ 0.7 K/W)	Acceptable where cost sensitivity outweighs efficiency targets; requires larger heatsink for same current.
STP110N4F6	R_DS(on) = 3.2 mΩ @ 10 V; V_DS = 40 V; TO-220; Q_G = 105 nC	Lower gate charge but higher R_DS(on); not qualified to 175 °C (max T_j = 175 °C not guaranteed)	Better for high-frequency switching where gate drive loss dominates; unsuitable for extended high-temp industrial use.

Compared with IRF1404PBF and STP110N4F6, PSMN2R2-40PS offers the lowest R_DS(on) and highest temperature qualification, making it optimal for space-constrained, high-efficiency, and thermally demanding applications-especially where long-term reliability at elevated ambient temperatures is required.

FAQ

Is PSMN2R2-40PS suitable for high-frequency switching above 1 MHz?

No. While its t_d(off) and t_f are fast (66.6 ns and 25.2 ns), its Q_G(tot) = 110–130 nC and C_iss = 8423 pF result in excessive gate drive power and switching loss above ~500 kHz. It is optimized for 100–500 kHz industrial and server power applications-not RF or resonant topologies.

Can PSMN2R2-40PS be used in automotive applications?

No. This part is not AEC-Q101 qualified and lacks automotive-specific validation. Nexperia explicitly states non-automotive qualification in its legal disclaimers. Use only in industrial, computing, or communications equipment-not in safety-critical or vehicle subsystems.

What is the maximum recommended gate resistor for reliable switching?

A 1.5 Ω external gate resistor is validated in the datasheet for t_d(off)/t_f measurements. For robust EMI control and oscillation suppression, 2.2–4.7 Ω is recommended. Values below 1 Ω increase risk of gate ringing and overshoot due to internal R_G = 1 Ω and package inductance.

Does the TO-220AB package require electrical isolation from the heatsink?

Yes. Pin 2 (drain) and the metal mounting base are electrically connected. If the heatsink is grounded or at a different potential than the drain node, an isolating pad (e.g., mica or silicone) and shoulder washer must be used to prevent short circuits and ensure safe operation.
