Nexperia USA Inc. PSMN2R1-30YLEX

Overview

PSMN2R1-30YLE from Nexperia is an N-channel 30 V ASFET in LFPAK56 (SOT669) package, engineered for hot-swap, e-fuse, and linear-mode load switching with enhanced Safe Operating Area (SOA). It delivers 2.2 mΩ R_DS(on) at V_GS = 10 V / T_j = 25 °C, supports 160 A continuous drain current at T_mb = 25 °C, and features copper-clip construction for low parasitic inductance - deployed in 12–20 V server backplane power rails.

For engineers reviewing the PSMN2R1-30YLE datasheet, PSMN2R1-30YLE pinout, PSMN2R1-30YLE application, or PSMN2R1-30YLE equivalent, key selection criteria include SOA robustness in linear mode, thermal resistance to mounting base (R_th(j-mb) = 0.69 K/W typ), gate charge profile (Q_G(tot) = 17 nC typ at 4.5 V), and LFPAK56 footprint compatibility with high-current PCB layouts.

Technical Context

This ASFET uses a trench-gate silicon process optimized for stable R_DS(on) over temperature (±3.3 mV/K threshold drift) and high avalanche ruggedness (E_AS = 309 mJ unclamped). Its SOA curve is validated up to 672 A peak pulsed current at V_DS = 10 V with 10 µs pulse width, enabling reliable inrush limiting without external current sensing.

The device integrates a low-leakage body diode (I_DSS < 1 µA at 25 °C) with soft reverse recovery (S = 0.99) and low Q_r = 15 nC, reducing voltage overshoot during turn-off in bidirectional load-switch configurations. Gate drive is compatible with standard 4.5 V logic-level controllers due to V_GS(th) = 1.91 V typ and plateau voltage of 3.8 V.

Key Specifications

Pinout & Package

LFPAK56 (SOT669) is a 4-terminal, single-ended surface-mount package with exposed mounting base connected to drain. Its 30 mm² footprint delivers superior thermal and electrical performance versus SO-8, enabled by copper-clip interconnect and low-inductance source/gate layout.

FAQ

What is the maximum continuous drain current rating for PSMN2R1-30YLE?

The datasheet specifies 160 A continuous drain current at T_mb = 25 °C, verified in application testing. In real-world designs, this value is constrained by PCB copper area, thermal interface material, and ambient temperature - typical derated values range from 80 A at T_mb = 100 °C to 119 A at T_mb = 100 °C per Figure 2. Thermal design must prioritize mounting base cooling to sustain high current.

Does PSMN2R1-30YLE require a gate driver for hot-swap applications?

No external gate driver is required for basic hot-swap soft-start: its 1.91 V V_GS(th) and 17 nC Q_G(tot) allow direct drive from 3.3 V or 5 V MCUs using RC-based gate ramping. However, for sub-10 µs fault response in e-fuse mode, a dedicated gate driver (e.g., Nexperia PMGD280UN) is recommended to achieve full 672 A pulsed current capability and minimize Miller-induced shoot-through.

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

LFPAK56 reduces R_th(j-mb) to 0.69 K/W (typ) versus ~1.5 K/W for SO-8, achieved via copper-clip die attach and direct mounting base connection to drain. This cuts junction-to-heatsink thermal resistance by >50 %, enabling 2.2× higher linear-mode current before thermal runaway - confirmed by SOA curves extending to 100 A at V_DS = 12 V with T_j ≤ 150 °C.

Can PSMN2R1-30YLE be used in bidirectional current paths?

Yes - its body diode exhibits soft reverse recovery (S = 0.99) and low Q_r = 15 nC, making it suitable for bidirectional load switches and OR-ing configurations. When used back-to-back, the device blocks reverse current up to 124 A (I_S) and withstands 309 mJ avalanche energy, enabling robust fault handling without external diodes or TVS clamps.
