PMEG4050ETP-QX

Single Diodes Overview

The PMEG4050ETP-QX is a silicon Schottky rectifier from Nexperia, designed for surface-mount applications in the SOD-128 (FlatPower) package. It features a single diode configuration with a maximum repetitive peak reverse voltage of 40 V and a continuous forward current rating of 5 A. The device exhibits a low forward voltage drop of 430 mV at rated current and supports a peak non-repetitive forward surge current of 70 A. Operating temperatures range from -55 °C to +175 °C, with a power dissipation capacity of 2.5 W.

Single Diodes Feature Summary

• Utilizes FlatPower technology for enhanced thermal performance and system robustness.
• Qualified to AEC-Q101 standards for automotive reliability requirements.
• Features ultra-low forward voltage to minimize conduction losses.

Single Diodes Applications

• Reverse battery protection circuits
• Free-wheeling rectification in DC-DC converters
• Power supply output rectification

Single Diodes Procurement Notes

Verify the specific suffix 'QX' against official Nexperia documentation to confirm it denotes the reel packaging variant rather than a different electrical specification. Ensure the part number matches the required automotive qualification status if applicable to your design. Cross-reference the 12NC code for accurate ordering details.

Single Diodes Selection Notes

Select this component when high current handling up to 5 A is required in a compact SMD footprint. The SOD-128 package offers superior heat dissipation compared to standard SOD-123 variants. Consider the 40 V rating for 12 V nominal systems and verify that the 175 °C junction temperature capability meets your thermal management strategy.

Single Diodes Part Context

This device belongs to the PMEG series of automotive-grade Schottky rectifiers. The series is characterized by low forward voltage and high surge current capability, specifically engineered for space-constrained automotive electronics. The FlatPower package provides a large copper pad for efficient thermal transfer to the PCB.
