1N5397

Overview

The onsemi 1N5397 is a standard recovery rectifier diode designed for general-purpose applications. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 600 V. The device utilizes a DO-15 axial through-hole package, supporting a maximum non-repetitive peak forward surge current of 50 A. Electrical characteristics include a maximum DC reverse leakage current of 5 uA at rated voltage and a typical forward voltage drop of 1.3 V at full load. The component operates within a junction temperature range of -50°C to +175°C.

Feature Summary

• Standard recovery rectification with low leakage current
• High thermal stability up to 175°C junction temperature
• Robust surge current handling capability

Applications

• General purpose rectification in power supplies
• Free-wheeling diodes in inductive circuits
• Polarity protection in electronic systems

Procurement Notes

Verify the manufacturer designation carefully, as the 1N5397 part number is widely produced by multiple semiconductor vendors including Diotec and Vishay. Confirm that the specific datasheet provided matches the onsemi manufacturing origin to ensure consistency in electrical parameters and quality standards. Cross-reference the ordering suffixes to identify the exact packaging configuration required for your assembly process.

Selection Notes

Select this component when a 600V blocking voltage and 1.5A continuous current rating are required in a standard axial package. Ensure the application does not demand ultra-fast switching speeds, as this is a standard recovery device. Verify that the thermal management strategy supports the specified maximum junction temperature limits under expected operating loads.

Part Context

This component belongs to the 1N53xx series of general-purpose silicon rectifiers. These devices are standardized across the industry for basic AC-to-DC conversion and DC circuit protection. The 1N5397 specifically addresses the 600V voltage tier within this family, offering a balance between voltage withstand capability and current carrying capacity for medium-power applications.

Replacement Considerations

Direct functional equivalents include the 1N5397 variants from Diotec Semiconductor and Vishay General Semiconductor. Other manufacturers producing the JEDEC 1N5397 specification can be used if their datasheets confirm identical or superior electrical ratings for voltage, current, and thermal performance.
