PMEG3020CPA-QX

Overview

The PMEG3020CPA-QX is a dual Schottky barrier rectifier in common cathode configuration, encapsulated in a SOT1061 (DFN2020-3) leadless small Surface-Mounted Device plastic package. It features an average forward current of 2 A and a reverse voltage rating of 30 V. The device exhibits a typical forward voltage of 410 mV at 2 A and 25 °C, with a maximum reverse current of 2000 µA at 30 V and 25 °C. Total power dissipation reaches 960 mW at 25 °C ambient temperature on a ceramic PCB.
