PMEG4050CEPX

Single Diodes Overview

The PMEG4050CEPX is a single Schottky barrier rectifier manufactured by Nexperia, designed for surface-mount applications. It features a CFP5 (SOD-128) package with solderable side pads. Key electrical parameters include a maximum repetitive peak reverse voltage of 40 V and a continuous forward current of 5 A. The device exhibits a typical forward voltage of 620 mV at rated current and supports a non-repetitive peak forward surge current of 70 A. It operates within a junction temperature range from -55°C to +175°C and has a maximum reverse leakage current of 300 µA.

Single Diodes Feature Summary

• Planar Schottky barrier technology with integrated guard ring for enhanced stress protection
• Low forward voltage characteristic to improve system efficiency
• High thermal stability allowing operation up to 175°C junction temperature
• Leadless SMD plastic package with visible and solderable side pads for robust mounting

Single Diodes Applications

• Low voltage rectification in power supply circuits
• High efficiency DC-to-DC conversion modules
• Reverse polarity protection for sensitive electronic loads
• Switch mode power supply output stages

Single Diodes Procurement Notes

Verify the specific suffix CEPX against official Nexperia documentation to confirm the exact tape-and-reel packaging configuration and marking codes. Ensure the procurement channel provides valid traceability for automotive or industrial grade requirements if applicable. Cross-reference the datasheet revision date to confirm compliance with current RoHS and REACH standards before finalizing orders.

Single Diodes Selection Notes

Select this component when a 5 A current rating and 40 V blocking capability are required in a compact SOD-128 footprint. The low forward voltage makes it suitable for high-efficiency designs where conduction losses must be minimized. Consider the 175°C maximum junction temperature for high-temperature environments. Compare surge current ratings against potential inrush conditions in the target application circuit.

Single Diodes Part Context

This part belongs to the MEGA (Maximum Efficiency General Application) series of Schottky rectifiers from Nexperia. The series focuses on combining low forward voltage with high reliability through planar technology. The PMEG4050CEPX specifically targets applications requiring higher current handling than smaller packages while maintaining a small board area compared to traditional axial leads.

Single Diodes Replacement Considerations

Direct replacements must match the 40 V / 5 A rating and SOD-128/CFP5 package. Verify that substitute components offer comparable forward voltage and reverse leakage characteristics. Check for equivalent thermal resistance and surge current capabilities to ensure circuit performance remains unchanged during substitution.
