Product details

Overview

PSMN027-100PS from Nexperia is a standard-level N-channel MOSFET in TO-220AB (SOT78) package, rated for 100 V drain-source voltage, 26.8 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and qualified to 175 °C junction temperature. It delivers 37 A continuous drain current at T_mb = 25 °C and supports high-efficiency power switching in server PSUs and motor control circuits.

For engineers reviewing the PSMN027-100PS datasheet, PSMN027-100PS pinout, PSMN027-100PS application, or PSMN027-100PS equivalent, this device is selected for its low conduction loss, standard gate drive compatibility (V_GS(th) = 2–4 V), avalanche ruggedness (59 mJ), thermal robustness (R_th(j-mb) = 0.8–1.46 K/W), and proven use in DC-DC converters requiring stable 100 V-class switching.

Technical Context

This MOSFET employs planar silicon technology with optimized channel geometry to achieve low R_DS(on) while maintaining robust safe operating area (SOA) up to 148 A pulsed drain current. Its gate threshold voltage (2–4 V typ.) ensures reliable turn-on with standard 10 V logic-level drivers without requiring level-shifting circuitry.

The device integrates an intrinsic body diode with 0.8–1.2 V forward voltage at 15 A and 47 ns reverse recovery time, enabling synchronous rectification and freewheeling operation in hard-switched topologies. Thermal resistance from junction to mounting base (0.8–1.46 K/W) enables direct heatsink mounting for high-power dissipation up to 103 W at T_mb = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	100 V - Maximum blocking voltage for 100 V bus applications including server PSUs and industrial DC-DC stages.
R_DS(on)	26.8 mΩ @ V_GS = 10 V, I_D = 15 A, T_j = 25 °C - Enables <1 W conduction loss at 20 A, critical for high-efficiency power conversion.
I_D	37 A @ T_mb = 25 °C - Supports high-current load switching and motor phase legs without parallel devices.
Q_G(tot)	30 nC - Low total gate charge reduces driver power demand and switching losses in 100–500 kHz SMPS designs.
E_AS	59 mJ - Unclamped avalanche energy rating allows robust operation under inductive switching stress without external snubbers.
T_j max	175 °C - Extended temperature qualification supports operation in sealed enclosures and high-ambient industrial environments.
R_th(j-mb)	0.8–1.46 K/W - Enables efficient thermal coupling to heatsinks, supporting >80 W continuous dissipation with modest heatsinking.

Pinout & Package

Package: TO-220AB (SOT78), plastic single-ended package with heatsink-mounted mounting base electrically connected to the drain terminal.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control input; requires ≤20 V gate-source voltage; threshold 2–4 V enables standard logic-level drive.
2 (D)	Drain	Main high-side switching node; internally bonded to mounting base for direct heatsink attachment and thermal path.
3 (S)	Source	Power return path; referenced to gate drive ground; forms common node for source sensing and current monitoring.

Key Features

Feature	Design Value
Standard-level gate drive	Operates reliably with 10 V gate drive-no dedicated gate driver IC required in most 12/24/48 V systems.
Low R_DS(on) × Q_G figure of merit	26.8 mΩ × 30 nC = 0.804 Ω·nC-optimized trade-off between conduction and switching loss for 100–300 kHz operation.
Avalanche-rated	59 mJ non-repetitive E_AS-enables robustness against inductive kickback in motor control and relay driving.
High-temperature qualification	175 °C T_j max and R_DS(on) drift <2.8× from 25 °C to 175 °C-ensures stable performance in thermally constrained designs.
Body diode with fast recovery	t_rr = 47 ns, Q_r = 91 nC-reduces reverse recovery loss and EMI in freewheeling and synchronous rectifier roles.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel MOSFET switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP110N10F7	100 V, 110 A, 9.5 mΩ R_DS(on), DPAK package, 175 °C rated	Higher current capability but smaller package limits thermal dissipation; requires more complex PCB layout for heatsinking.	Select when higher peak current (>50 A) is needed and board space permits multi-layer thermal pads.
IRF540NPBF	100 V, 33 A, 44 mΩ R_DS(on), TO-220 package, 175 °C rated	Higher R_DS(on) increases conduction loss by ~65 %; identical pinout and footprint but lower efficiency at >15 A.	Choose only for legacy design reuse where 44 mΩ loss is acceptable and cost sensitivity outweighs efficiency targets.

Compared with STP110N10F7 and IRF540NPBF, PSMN027-100PS offers optimal balance of low R_DS(on) (26.8 mΩ), TO-220 thermal performance (0.8 K/W), and standard gate drive-making it superior for new 20–40 A industrial power designs where efficiency and thermal margin are prioritized.

FAQ

Is PSMN027-100PS suitable for automotive applications?

No. The datasheet explicitly states this device is not automotive-qualified. It lacks AEC-Q101 certification, has no automotive-specific reliability testing, and is intended for industrial, communications, and domestic equipment per its qualification scope. Automotive use requires explicit Nexperia automotive-grade variants such as the PSMN2R0-100PSL.

What is the maximum gate-source voltage rating?

The absolute maximum V_GS is ±20 V, as specified in Table 4 (Limiting Values). Operation beyond this range risks permanent gate oxide damage. For reliable long-term performance, gate drive should be limited to 12–15 V with appropriate transient suppression, especially in noisy industrial environments.

How does the mounting base connection affect PCB layout?

The mounting base (pin 2/D) is electrically connected to the drain terminal. This requires isolation of the heatsink from other potentials and careful clearance routing on the PCB-especially under the TO-220 tab-to avoid short circuits. A mica or ceramic insulator plus thermal grease is mandatory if the heatsink is grounded or at a different potential.

Can PSMN027-100PS replace IRF540N in existing designs?

Yes, with verification. Both share TO-220AB pinout and 100 V rating, but PSMN027-100PS has lower R_DS(on) (26.8 mΩ vs. 44 mΩ) and higher ID (37 A vs. 33 A), improving efficiency and thermal headroom. Gate threshold is similar (2–4 V), so existing 10 V drivers remain compatible. Layout and thermal validation are recommended before full replacement.
