PMEG4005CEAX

Single Diodes Overview

The PMEG4005CEAX is a planar Schottky barrier rectifier from Nexperia, housed in an SOD323 (SC-76) surface-mount package. It features an integrated guard ring for stress protection. Key electrical parameters include a maximum reverse voltage of 40 V and an average forward current rating of 0.5 A. The typical forward voltage is 550 mV at 500 mA, with a typical reverse current of 1.5 µA at 40 V. The device supports junction temperatures up to 150 °C and storage temperatures ranging from -65 °C to 150 °C.

Single Diodes Feature Summary

• Planar Schottky barrier technology with integrated guard ring for enhanced stress protection
• Low forward voltage characteristics for improved efficiency
• Very small SMD plastic package footprint
• Low reverse current leakage

Single Diodes Applications

• Low voltage rectification
• High efficiency DC-to-DC conversion
• Switch Mode Power Supply (SMPS)
• Reverse polarity protection
• Low power consumption applications

Single Diodes Procurement Notes

Verify the specific ordering suffix 'AX' against official Nexperia documentation to confirm tape-and-reel packaging details, as datasheets typically list the base part number PMEG4005CEA. Confirm non-automotive qualification status if used in automotive environments. Ensure thermal management aligns with the specified junction temperature limits and PCB mounting requirements.

Single Diodes Selection Notes

Select this component for circuits requiring low forward voltage drop and compact surface-mount integration. The 40 V reverse voltage rating suits low-voltage systems. Consider the thermal resistance values when designing heat dissipation paths on FR4 PCBs. Verify that the 0.5 A average current rating meets the peak load requirements of the target application without exceeding absolute maximum ratings.

Single Diodes Part Context

This device belongs to the Nexperia PMEG4005 series of low VF Schottky barrier rectifiers. The series includes variants with different packages such as SOT23 and SOD962. The PMEG4005CEA specifically utilizes the SOD323 package, distinguishing it from other series members by its physical dimensions and pin pitch while maintaining similar electrical performance characteristics.

Single Diodes Replacement Considerations

Check for direct substitutes within the PMEG4005 series, such as PMEG4005CT or PMEG4005ESFYL, ensuring package compatibility and identical electrical specifications before substitution.
