PMEG2020CPASX

Overview

The PMEG2020CPASX is a planar Schottky barrier rectifier in a common cathode configuration, featuring an integrated guard ring for stress protection. It is encapsulated in the DFN2020D-3 (SOT1061D) leadless small Surface-Mounted Device plastic package with visible and solderable side pads. The device supports an average forward current of 2 A and a reverse voltage of 20 V. Key electrical parameters include a maximum forward voltage of 420 mV at 2 A and a maximum reverse current of 1000 µA at 20 V.

• Switch Mode Power Supply (SMPS)
• Free-wheeling application
• Reverse polarity protection

Procurement Notes

Verify that the specific part number PMEG2020CPASX corresponds to the non-automotive qualified version as indicated in the latest datasheet revision history. Confirm the package type is DFN2020D-3 and ensure compatibility with automatic optical inspection requirements due to the visible side pads. Cross-reference the marking code CW to confirm authenticity upon receipt.

Selection Notes

Select this component for designs requiring low forward voltage drop and efficient thermal dissipation in compact layouts. The exposed cathode pad facilitates heat sinking on FR4 or ceramic PCBs. Ensure the operating junction temperature remains within the specified limits and consider the transient thermal impedance characteristics when designing for pulsed current applications.

Part Context

This component belongs to Nexperia's PMEG series of low VF dual Schottky barrier rectifiers. It utilizes the DFN2020D-3 package, which is designed to reduce printed-circuit-board area requirements while maintaining robust performance. The series is engineered for high-efficiency power management solutions where space constraints and thermal management are critical design factors.

Replacement Considerations

For automotive applications, verify if the -Q variant is required, as this specific part is not automotive qualified. Check pinout compatibility with existing footprints before substitution.
