Product details

Overview

PSMN8R7-100YSFX from Nexperia is a 100 V, 9 mΩ N-channel MOSFET in LFPAK56 (SOT669) package, qualified to 175 °C junction temperature, featuring low Q_G × R_DS(on) figure-of-merit (38.5 nC total gate charge, 7.2 mΩ typical R_DS(on) at 25 °C), strong avalanche rating (234 mJ), and wave-solderable construction. It serves as a high-efficiency switching device in synchronous rectification and half-bridge topologies for AC-DC adapters and BLDC motor drives.

For engineers reviewing the PSMN8R7-100YSFX datasheet, PSMN8R7-100YSFX pinout, PSMN8R7-100YSFX application, or PSMN8R7-100YSFX equivalent, this page delivers verified electrical parameters, thermal resistance (0.67 K/W j-mb), avalanche ruggedness, diode recovery characteristics (52.6 nC Q_r), and LFPAK56 mounting-base thermal interface details critical for power stage layout and reliability validation.

Technical Context

This NextPower MOSFET uses a trench-gated silicon process optimized for low conduction and switching losses in hard-switched and resonant converters. Its 100 V V_DS rating supports 48 V industrial bus and USB-PD 3.1 EPR input stages, while the 175 °C T_j qualification enables operation in thermally constrained enclosures without derating.

The device integrates an intrinsic body diode with 45.5 ns reverse recovery time and 0.8–1.2 V forward voltage at 25 A, enabling reliable synchronous rectification without external Schottky diodes. Gate threshold voltage (2–4 V) and plateau voltage (4.9 V) support standard 5 V or 10 V gate drivers without level-shifting.

Key Specifications

Pinout & Package

LFPAK56 (SOT669) is a 4-lead surface-mount plastic package with exposed mounting base connected to drain, offering superior thermal and power cycling performance versus SO-8. The package is wave-solderable and features 3 parallel source terminals for low-inductance, high-current routing.

Pin/Terminal	Circuit Role	Design Meaning
1	Source	Primary low-side return path; tied internally to pins 2 and 3 for reduced source inductance in high-dI/dt switching.
2	Source	Redundant source connection to minimize loop inductance and improve EMI in half-bridge layouts.
3	Source	Third source terminal enabling symmetric PCB layout and balanced current sharing across three copper pours.
4	Gate	Control input with 0.8 Ω internal gate resistance; requires <5 Ω external series resistor for optimal ringing suppression.
Mounting Base	Drain	Exposed copper pad electrically connected to drain; provides primary thermal path to PCB and must be soldered to ≥ 200 mm² copper area.

Key Features

Feature	Design Value
Low Q_rr	52.6 nC - Reduces turn-on loss and voltage overshoot in synchronous rectifiers operating at >100 kHz.
175 °C qualification	Rated for continuous operation up to 175 °C junction temperature - eliminates thermal derating in compact LED drivers and fast-charge adapters.
Low Q_G × R_DS(on)	277 - Industry-leading figure-of-merit enabling high efficiency in both conduction- and switching-limited designs.
Avalanche energy rating	234 mJ - 100% tested unclamped avalanche capability ensures reliability in flyback and LLC resonant converters under overload.
Wave-solderable LFPAK56	Compatible with standard wave soldering profiles - eliminates reflow-only constraints in mixed-technology PCB assembly.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon IPP040N10N5	100 V, 4.0 mΩ R_DS(on), TO-220 package, 150 °C rated	Higher R_DS(on) but lower cost; larger footprint and inferior thermal resistance (1.2 K/W j-case)	Select when board space allows TO-220 and thermal budget permits higher junction rise.
ON Semiconductor NTMFS5C673NL	100 V, 6.7 mΩ R_DS(on), PowerTrench 5x6 mm package, 175 °C rated	Similar thermal performance (0.75 K/W j-tab), but higher Q_G (48 nC) increases driver loss	Prefer when existing layout uses 5x6 mm footprint and gate drive strength exceeds 1 A peak.

Compared with IPP040N10N5 and NTMFS5C673NL, PSMN8R7-100YSFX offers the lowest R_DS(on) × Q_G product (277 vs. 360 and 320), best thermal resistance (0.67 K/W), and wave-solder compatibility - making it optimal for high-density, high-reliability adapter and motor-control designs where PCB assembly flexibility matters.

FAQ

What is the maximum continuous drain current for PSMN8R7-100YSFX at 100 °C mounting base temperature?

At T_mb = 100 °C, the continuous drain current is 71 A per the datasheet Fig. 2. This value accounts for thermal derating due to reduced heat transfer from junction to mounting base at elevated temperatures, and assumes proper PCB copper area (≥ 200 mm²) and no forced airflow.

Is PSMN8R7-100YSFX suitable for use in automotive applications?

No - PSMN8R7-100YSFX is not AEC-Q101 qualified and is explicitly designated for industrial and consumer applications. Nexperia's documentation states non-automotive qualified products are unsuitable for safety-critical or life-support systems, and automotive use voids warranty and liability coverage.

How does the LFPAK56 package improve thermal performance compared to standard SO-8?

The LFPAK56 exposes the drain-connected mounting base directly to the PCB, achieving 0.67 K/W junction-to-mounting-base thermal resistance - nearly 2× better than SO-8's typical 1.3 K/W. This enables 198 W power dissipation at T_mb = 25 °C without a heatsink, reducing system size and cost in high-power adapters.

What is the significance of the 100% avalanche testing for PSMN8R7-100YSFX?

Every unit undergoes unclamped inductive switching test at I_AS = 30.3 A and E_AS = 234 mJ, verifying robustness against transient overcurrents in flyback, LLC, and motor-drive circuits. This eliminates field failures due to single-event avalanche stress and supports design without external snubbers in many topologies.
