PMEG2020CPA-QX

Overview

The PMEG2020CPA is a planar Schottky barrier rectifier in a common cathode configuration, encapsulated in a DFN2020-3 (SOT1061) leadless SMD plastic package. It features an integrated guard ring for stress protection and an exposed heat sink (cathode pad). The device supports an average forward current of 2 A and a reverse voltage of 20 V. Key electrical parameters include a typical forward voltage of 385 mV at 2 A and 25 °C, with a maximum of 420 mV. Reverse current is typically 380 µA at 20 V and 25 °C.

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and availability status. Confirm that the component meets the required AEC-Q101 qualification standards for your target application environment. Ensure design compatibility with the DFN2020-3 footprint and reflow soldering profiles specified in the datasheet before finalizing procurement.

Selection Notes

Select this component for designs requiring low forward voltage drop and high current density in a compact form factor. The exposed cathode pad necessitates careful PCB layout optimization for thermal management. Verify that the operating junction temperature remains within the 150 °C limit under worst-case ambient conditions and duty cycles.
