PMEG4010CPA,115

Overview

The PMEG4010CPA is a 40 V, 1 A low forward voltage dual Schottky barrier rectifier in a common cathode configuration. It features an integrated guard ring for stress protection and is encapsulated in a DFN2020-3 (SOT1061) leadless SMD plastic package with an exposed heat sink. The device supports an average forward current of 1 A and a reverse voltage of 40 V. At 25 °C junction temperature, the typical forward voltage is 440 mV at 1 A, with a maximum reverse current of 55 µA at 40 V.

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as standard data sheets may not detail tape-and-reel specifications. Confirm that the DFN2020-3 footprint aligns with your PCB design guidelines. Ensure compliance with AEC-Q101 requirements if deploying in automotive environments. Validate thermal management strategies against the provided transient thermal impedance curves for your specific mounting conditions.

Selection Notes

Select this component for applications requiring low forward voltage drop to maximize efficiency in power conversion circuits. The common cathode arrangement simplifies circuit design for dual-diode needs. Consider the exposed pad for thermal dissipation when calculating power losses. Verify that the 40 V reverse voltage rating exceeds the peak inverse voltage in the target application to ensure reliable operation under all conditions.
