Nexperia USA Inc. PMPB12R5UPEX

Overview

PMPB12R5UPEX 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 13 A continuous drain current at V_GS = −4.5 V, 11.8 mΩ typical R_DS(on) at 25 °C, −20 V drain-source voltage rating, and features an exposed drain pad for thermal conduction in battery-powered charging switches and DC-DC converters.

For engineers reviewing the PMPB12R5UPEX datasheet, PMPB12R5UPEX pinout, PMPB12R5UPEX application, or PMPB12R5UPEX equivalent, key selection criteria include low-threshold gate drive compatibility with 1.8–2.5 V logic, ultra-thin 0.65 mm profile for stacked PCBs, ESD robustness (>2000 V HBM), and thermal performance on FR4 with 6 cm² drain pad.

Technical Context

This device operates as a high-side load switch in battery management systems, leveraging its negative threshold voltage (−0.6 V typ) to enable direct control from low-voltage microcontrollers without level-shifting. Its trench architecture minimizes conduction losses while maintaining fast switching: 5 ns turn-on delay, 44 ns fall time, and 26 nC total gate charge support efficient PWM operation in portable DC-DC stages.

The DFN2020M-6 package integrates five drain terminals and one source terminal on the bottom side, with gate and source accessible via top-side pads - enabling compact layout and low-inductance source return paths. Thermal resistance from junction to solder point is 6–10 K/W, confirming suitability for thermally demanding 2×2 mm footprint applications where heatsinking area is limited.

FAQ

What is the maximum continuous drain current for PMPB12R5UPEX at 100 °C ambient temperature?

The maximum continuous drain current is −5.9 A at T_amb = 100 °C with V_GS = −4.5 V, as specified in Table 5 (Limiting Values). This derating reflects thermal constraints on standard FR4 PCBs with 6 cm² drain pad; actual current depends on board layout and airflow.

Can PMPB12R5UPEX be driven directly from a 1.8 V microcontroller GPIO?

Yes - its typical V_GS(th) of −0.6 V and guaranteed −0.4 V minimum allow full enhancement at 1.8 V drive. At V_GS = −1.8 V, R_DS(on) is 22–35 mΩ (Table 7), supporting ≤4 A loads with acceptable conduction loss in low-duty-cycle applications.

Is the exposed drain pad electrically isolated or must it be connected to circuit ground?

The exposed drain pad is electrically connected to all drain terminals (pins 1, 2, 5, 6) and must be soldered to a PCB copper pour tied to the drain net - not ground. This connection provides both thermal conduction and low-inductance current return, critical for EMI and efficiency.

Does PMPB12R5UPEX include integrated body diode protection for reverse-current blocking?

Yes - it contains an intrinsic source-drain diode with V_SD = −0.7 to −1.2 V at −1.8 A (Table 7). This diode enables reverse-current blocking in high-side switch configurations but is not rated for continuous forward conduction; external Schottky clamping is recommended for inductive flyback suppression.
