PMEG4005AEA/8X

Single Diodes Overview

The PMEG4005AEA/8X is a planar Schottky barrier rectifier manufactured by Nexperia, encapsulated in a SOD323 (SC-76) surface-mount package. It features an integrated guard ring for stress protection and offers a forward current of 0.5 A with a maximum reverse voltage of 40 V. The device exhibits a typical forward voltage of 420 mV at 500 mA and a maximum reverse current of 100 µA at 40 V. It supports a non-repetitive peak forward current of 10 A and operates within a junction temperature range of -65 °C to 150 °C.

Single Diodes Procurement Notes

Verify the specific ordering suffix '/8X' against official Nexperia documentation to confirm reel quantity or tape specifications, as standard datasheets typically list the base part number PMEG4005AEA. Confirm RoHS compliance status and ensure the component meets automotive qualification requirements if intended for such environments, as this specific variant is not explicitly stated as automotive qualified in the provided data.

Single Diodes Selection Notes

Select this component for designs requiring minimal footprint and low conduction losses in low-voltage circuits. The SOD323 package suits space-constrained PCB layouts. Ensure thermal management accounts for reverse power losses, as thermal runaway considerations are noted for Schottky diodes. Verify that the 40 V reverse voltage rating provides adequate margin for the specific application's peak inverse voltage conditions.

Single Diodes Part Context

This component belongs to the PMEG series of MEGA (Maximum Efficiency General Application) Schottky barrier rectifiers from Nexperia. These devices are designed for high-efficiency applications where low forward voltage drop is critical. The series utilizes planar technology with guard rings to enhance reliability under stress conditions compared to older generation Schottky diodes.
