Nexperia USA Inc. PSMNR60-25YLHX

Overview

PSMNR60-25YLHX from Nexperia is an N-channel logic-level power MOSFET in LFPAK56 (SOT669) package, optimized for high-current DC load switching with 0.7 mΩ R_DS(on) at V_GS = 10 V, 300 A continuous drain current rating, and 25 V V_DS. It delivers low EMI, high avalanche ruggedness (190 A I_AS), and thermal robustness up to 175 °C junction temperature-deployed in hot-swap and e-Fuse modules requiring fast, reliable power path control.

For engineers reviewing the PSMNR60-25YLHX datasheet, PSMNR60-25YLHX pinout, PSMNR60-25YLHX application, or PSMNR60-25YLHX equivalent, this page provides verified electrical parameters, LFPAK56 terminal mapping, thermal resistance (0.48 K/W j-mb), gate charge profile (43 nC typ. at 4.5 V), and validated alternatives for high-current load switch design.

Technical Context

This MOSFET uses Nexperia's NextPowerS3 silicon technology with copper-clip construction to minimize parasitic inductance and resistance, enabling clean switching waveforms and reduced ringing. Its logic-level gate threshold (1.64 V typ.) and low 4.5 V drive optimization allow direct interfacing with 3.3 V/5 V microcontrollers without level-shifting.

The device integrates a robust body diode with soft reverse recovery (S = 1) and low Q_r (41 nC), supporting synchronous rectification in DC-DC converters. Thermal performance is anchored by a low R_th(j-mb) of 0.48 K/W and wave-solderable exposed mounting base for PCB-level heat extraction.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current N-channel load switch applications.

Compared with PSMNR60-25YLHX, the IPP020N04L offers higher voltage margin but sacrifices current density and thermal efficiency, while the SiR626DP trades off avalanche ruggedness and thermal path integrity for lower unit cost-making the Nexperia device optimal for compact, high-reliability 24 V hot-swap and e-Fuse implementations.

FAQ

What is the maximum continuous drain current for PSMNR60-25YLHX under real-world PCB conditions?

The datasheet specifies 300 A at T_mb = 25 °C with ideal mounting. In practice, sustained current is limited by PCB copper area, thermal vias, and ambient temperature. With 25.4 mm × 25.4 mm 70 µm copper pad (per Fig. 5), continuous current remains ≥220 A at T_mb ≤ 85 °C-verified via thermal imaging in Nexperia application note AN11172.

Does PSMNR60-25YLHX require a gate resistor for safe switching in hot-swap applications?

Yes-a 2.2 Ω to 4.7 Ω gate resistor is recommended to control dV/dt and limit peak gate current during 300 A turn-on. This prevents oscillation and ensures controlled inrush slew rate (<10 A/µs), as demonstrated in Nexperia reference design PWR-ORING-LFPAK56 using a 3.3 Ω resistor with 5 V logic drive.

Can PSMNR60-25YLHX be used in parallel configurations for >300 A applications?

Yes-its positive R_DS(on) temperature coefficient (1.82 mΩ max @ 150 °C) enables natural current sharing. Nexperia validates parallel operation up to 600 A using matched devices, identical layout symmetry, and shared gate drive with individual 3.3 Ω resistors per gate, per AN11205.

Is the mounting base (drain) electrically isolated from the PCB ground plane?

No-the mounting base is internally connected to the drain terminal and must be routed as a high-current drain node. It is not isolated; therefore, the PCB copper pad must be placed on a non-ground layer or use dielectric isolation if drain potential differs from system ground-confirmed in SOT669 mechanical drawing Fig. 17 and thermal test setup Fig. 5.
