Nexperia USA Inc. PMZ370UNEZ

Overview

PMZ370UNE from Nexperia is a 30 V, N-channel enhancement-mode Trench MOSFET in a DFN1006-3 (SOT883) ultra-small surface-mount package, designed for low-side load switching and high-speed line driving. It delivers R_DS(on) = 370 mΩ at V_GS = 4.5 V and I_D = 500 mA, features ESD protection >2 kV HBM, and operates across -55 °C to 150 °C junction temperature.

For engineers reviewing the PMZ370UNE datasheet, PMZ370UNE pinout, PMZ370UNE application, or PMZ370UNE equivalent, key selection criteria include its 1.0 × 0.6 mm footprint, low 0.77 nC total gate charge, fast 11 ns turn-on delay, and suitability for space-constrained DC-DC converter control, portable USB power switches, and battery-powered sensor node load management.

Technical Context

This MOSFET uses Trench technology to achieve low threshold voltage (0.5–1.05 V) and stable R_DS(on) over temperature-650 mΩ max at T_j = 150 °C. Its gate drive compatibility with 1.8 V logic enables direct interfacing with modern microcontrollers and low-voltage I/Os.

The device integrates an intrinsic source-drain diode (V_SD = 0.48–1.2 V at I_S = 300 mA), supports peak drain current up to 3.6 A (10 µs pulse), and exhibits low output capacitance (C_oss = 9 pF) and reverse transfer capacitance (C_rss = 3 pF), enabling efficient high-frequency switching.

FAQ

Is PMZ370UNE suitable for 1.8 V logic-level gate drive?

Yes. With a typical V_GS(th) of 0.77 V and guaranteed turn-on at V_GS ≥ 1.8 V, PMZ370UNE fully enhances at 1.8 V, delivering R_DS(on) ≤ 750 mΩ at I_D = 400 mA and T_j = 25 °C-making it compatible with modern ultra-low-voltage MCUs without gate drivers.

What is the thermal resistance when mounted on a standard FR4 PCB?

When mounted on a single-sided FR4 PCB with a 1 cm² tin-plated copper drain pad, R_th(j-a) is 305 K/W typical. This allows 500 mA continuous current with a junction-to-ambient temperature rise of ~154 °C-well within the 150 °C absolute maximum if ambient remains ≤25 °C.

Does PMZ370UNE have integrated ESD protection?

Yes. It features built-in Human Body Model (HBM) ESD protection rated >2 kV per JESD22-A114, verified across all pins. No external TVS diodes are required for standard handling or board-level ESD immunity in Class 1B environments.

Can PMZ370UNE replace older SOT23 MOSFETs in existing designs?

It can serve as a footprint-downgrade replacement where board space is constrained-but requires layout revision: DFN1006-3 has no leads and demands precise stencil design, solder paste volume control, and thermal pad routing. Electrical specs exceed many SOT23 equivalents, but mechanical fit is not drop-in.
