Nexperia USA Inc. PMPB20XPEAX

Overview

PMPB20XPEA from Nexperia is a P-channel enhancement-mode Trench MOSFET in DFN2020MD-6 (SOT1220) package, rated for −20 V drain-source voltage, 7.2 A continuous drain current at V_GS = −4.5 V, and 19 mΩ typical R_DS(on) at T_j = 25 °C. It serves as a high-side load switch or relay driver in automotive and industrial power control circuits.

For engineers reviewing the PMPB20XPEA datasheet, PMPB20XPEA pinout, PMPB20XPEA application, or PMPB20XPEA equivalent, this device is selected for low-threshold switching in space-constrained 12 V systems requiring AEC-Q101 qualification, side-wettable flanks for solder inspection, and robust ESD protection (>2 kV HBM).

Technical Context

This MOSFET uses Trench technology to achieve low R_DS(on) and fast switching with 30 nC typical total gate charge and 7.1 nC gate-drain charge. Its −0.7 V typical gate threshold voltage enables direct interface with 1.8 V–3.3 V logic controllers without level shifting.

The device integrates a body diode with 1.2 V max forward voltage at −1.9 A and 31 ns reverse recovery time, supporting synchronous rectification and inductive load commutation. Thermal resistance from junction to solder point is 67 K/W, optimized for PCB-mounted thermal relief via its exposed drain pad.

FAQ

Is PMPB20XPEA suitable for 12 V automotive battery monitoring circuits?

Yes. With −20 V V_DS, AEC-Q101 qualification, and operation down to −55 °C ambient, PMPB20XPEA is designed for direct integration into 12 V battery-connected subsystems such as junction box controllers and battery disconnect switches. Its low R_DS(on) ensures minimal voltage drop during cranking conditions.

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

The datasheet specifies −4.5 A continuous drain current at T_amb = 100 °C with V_GS = −4.5 V. This derating reflects thermal limits of the DFN2020MD-6 package on standard FR4; actual current depends on PCB copper area and airflow, but the normalized curve (Fig. 2) confirms 60% current retention at 100 °C.

Does PMPB20XPEA require a gate resistor for 1 MHz PWM operation?

A 6 Ω external gate resistor was used in the datasheet's switching time test (td(on), tr, etc.), confirming compatibility with 1 MHz PWM. For robust EMI control and ringing suppression, a 5–10 Ω series resistor is recommended-especially when driving inductive loads or operating near layout parasitics.

Can PMPB20XPEA replace an N-channel MOSFET in a high-side configuration without additional components?

No. As a P-channel device, PMPB20XPEA operates as a high-side switch with gate driven below source potential-but it still requires proper gate control logic (e.g., inverter or dedicated high-side driver) to achieve full enhancement. Unlike N-channel solutions, it avoids bootstrap complexity but needs correct level-shifting for 0 V–3.3 V control signals.
