HPZR-C39X

Single Zener Diodes Overview

The Nexperia HPZR-C39X is a high power voltage regulator diode housed in a CFP3 (SOD123W) surface-mounted package. It provides a nominal Zener voltage of 39 V with a tolerance of approximately ±5 %. The device supports a maximum total power dissipation of 4.1 W at a solder point temperature of 75 °C, or 962 mW under standard ambient conditions. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA and a differential resistance of 49.82 Ω at a test current of 20 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify the specific part number suffix against official Nexperia documentation to confirm exact tolerance grades and marking codes. Ensure that thermal design calculations account for the required solder point temperature limits to maintain the specified power dissipation ratings during operation.

Single Zener Diodes Selection Notes

Select this component when high power handling is required within a small footprint. The CFP3 package allows for significant heat sinking through the cathode tab. Confirm that the operating junction temperature remains within the specified range to ensure long-term reliability and consistent voltage regulation performance.

Single Zener Diodes Part Context

This device belongs to the HPZR series of high power voltage regulator diodes manufactured by Nexperia. The series utilizes a CFP3 plastic package to deliver superior thermal performance compared to standard small signal diodes, making it suitable for applications demanding robust voltage stabilization in space-constrained environments.
