Nexperia USA Inc. PMPB19R0UPEX

Overview

PMPB19R0UPEX from Nexperia is a P-channel enhancement-mode Trench MOSFET in a DFN2020M-6 (SOT1220-2) package, designed for high-efficiency power switching in space-constrained portable electronics. It delivers 20 V drain-source voltage rating, 17 mΩ typical R_DS(on) at V_GS = −4.5 V and I_D = −7.6 A, and supports −11 A continuous drain current at T_amb = 25 °C - enabling compact battery charging switches and DC-DC converter high-side control.

For engineers reviewing the PMPB19R0UPEX datasheet, PMPB19R0UPEX pinout, PMPB19R0UPEX application, or PMPB19R0UPEX equivalent, key selection criteria include its ultra-thin 2 × 2 × 0.65 mm thermal-enhanced package, exposed drain pad for low R_th(j-sp) (7–10 K/W), ESD robustness (>2000 V HBM), and low gate threshold (−0.6 V typ) for 1.8 V logic-compatible drive.

Technical Context

This device uses Trench MOSFET technology to achieve low on-resistance and fast switching with minimal gate charge (Q_G(tot) = 16–24 nC). Its symmetrical drain-terminal layout (pins 1,2,5,6,7 all connected to drain) enables high-current routing and thermal spreading across the exposed pad.

The PMPB19R0UPEX operates as a high-side load switch or synchronous rectifier, leveraging its −0.6 V gate threshold and sub-1 V source-drain diode forward voltage (V_SD = −0.7 to −1.2 V at I_S = −1.7 A) to minimize conduction loss in battery management paths.

Key Specifications

Pinout & Package

DFN2020M-6 (SOT1220-2) is a leadless, ultra-thin surface-mount package measuring 2.0 × 2.0 × 0.65 mm with an exposed drain pad on the bottom for enhanced thermal dissipation. The top-side terminals are arranged in a single row of six positions, with pins 1, 2, 5, 6, and 7 all electrically connected to the drain - maximizing current-carrying capacity and thermal path efficiency.

FAQ

What is the maximum continuous drain current for PMPB19R0UPEX at 100 °C ambient temperature?

The PMPB19R0UPEX supports −4.8 A continuous drain current at T_amb = 100 °C, as specified in Table 5 (Limiting Values). This derating reflects thermal constraints under standard FR4 PCB mounting with 6 cm² drain copper, and aligns with the normalized current curve in Figure 2.

Does PMPB19R0UPEX require a gate resistor for safe switching in a 1 MHz DC-DC converter?

A gate resistor is recommended: the device's 8 Ω typical gate resistance and 16–24 nC total gate charge make it compatible with standard 5–10 Ω external gate resistors to control dV/dt, suppress ringing, and limit peak gate driver current to <1 A during 1 MHz switching.

Can PMPB19R0UPEX be used in automotive infotainment power rails?

No - the PMPB19R0UPEX is not AEC-Q101 qualified and is explicitly designated for consumer and industrial applications per Nexperia's legal disclaimers. Automotive use requires verified qualification, which this part does not hold.

How is thermal performance affected if the PCB lacks a 6 cm² drain copper pad?

Without the 6 cm² drain pad, R_th(j-a) degrades from 33–36 K/W to 235–270 K/W (Table 6), reducing continuous current capability from −11 A to ~−1.5 A at 25 °C ambient - necessitating strict thermal design validation using Figure 1 and Figure 4 data.
