1N5396

Overview

The onsemi 1N5396 is a general-purpose silicon rectifier diode designed for AC-to-DC conversion and freewheeling applications. It features an average forward current of 1.5 A and a maximum repetitive peak reverse voltage of 500 V. The device utilizes a DO-15 (DO-204AC) plastic axial package with molded epoxy construction rated UL 94V-0. Key electrical characteristics include a non-repetitive peak forward surge current of 50 A, a maximum DC blocking voltage of 350 V, and a maximum RMS voltage of 350 V. It operates within a junction temperature range of -65 °C to 175 °C.

Feature Summary

• Utilizes void-free molded plastic technique for mechanical stability
• Features low reverse leakage current for improved efficiency
• Capable of high forward surge currents for transient protection
• Guaranteed for high-temperature soldering processes

Applications

• General purpose rectification in power supplies
• Freewheeling diodes in inductive load circuits
• Inverter and converter input/output stages

Procurement Notes

Verify the specific manufacturer source, as the 1N5396 is a standard JEDEC part number produced by multiple vendors including Vishay, MCC, and others. Confirm that the ordered component matches the required 500 V reverse voltage rating and DO-15 package dimensions. Ensure compliance with RoHS directives if lead-free variants are specified for the assembly process.

Selection Notes

Select this component for circuits requiring a 1.5 A continuous current capacity with a 500 V reverse voltage standoff. The DO-15 package provides adequate thermal dissipation for general-purpose applications. Consider the 175 °C maximum junction temperature for high-ambient environments. Verify that the 50 A surge capability meets the inrush requirements of the specific power supply design.

Part Context

The 1N5396 belongs to the 1N539x series of glass-passivated or plastic general-purpose rectifiers. This series covers reverse voltages from 50 V to 1000 V, sharing common mechanical and thermal characteristics. The 1N5396 specifically addresses the 500 V requirement within this standardized lineup, ensuring interchangeability with other manufacturers' equivalents in the same voltage class.

Replacement Considerations

Direct substitutes include Vishay 1N5396GP/91-E3 and Micro Commercial Components 1N5396GP-AP. These equivalents maintain identical 1.5 A / 500 V ratings and DO-15 packaging. Verify pinout polarity and physical lead spacing compatibility before integration.
