PMEG3020CPAS-QX

Overview

The PMEG3020CPAS-QX is a dual Schottky barrier rectifier in common cathode configuration, encapsulated in an ultra-thin DFN2020D-3 (SOT1061D) leadless SMD plastic package. It features an integrated guard ring for stress protection and visible solderable side pads. The device supports an average forward current of 2 A per diode and a reverse voltage of 30 V. Forward voltage is typically 410 mV at 2 A, with a maximum reverse current of 2000 µA at 30 V. Total power dissipation reaches 960 mW on FR4 PCBs.

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm automotive qualification status. The base part number PMEG3020CPAS is explicitly designated as non-automotive qualified in the latest datasheet revision. Ensure the selected variant meets the required reliability standards for the target application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring low forward voltage drop and compact footprint. The exposed cathode pad facilitates efficient heat dissipation, supporting higher current densities in space-constrained layouts. Verify that the 30 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements and that the thermal resistance characteristics suit the board's cooling strategy.
