1N5397GH

Overview

The 1N5397GH is a standard recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a single diode configuration housed in an axial DO-204AC (DO-15) package designed for through-hole mounting. The device provides a maximum average forward rectified current of 1.5 A and supports a repetitive peak reverse voltage of 600 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 50 A, a typical reverse leakage current of 5 uA at rated voltage, and a maximum reverse recovery time of 1.5 us. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junction construction for enhanced reliability
• High current capability with low forward voltage drop
• Low leakage current performance under reverse bias conditions

Applications

• General purpose rectification in power supply circuits
• Freewheeling applications in inductive load protection
• DC-to-AC conversion stages in electronic equipment

Procurement Notes

Verify the specific suffix GH against official Taiwan Semiconductor documentation to confirm exact packaging and material specifications. Ensure compatibility with existing board layouts regarding the DO-15 footprint. Confirm environmental compliance status such as RoHS or halogen-free requirements prior to procurement. Cross-reference datasheet revisions to ensure parameter consistency with design specifications.

Selection Notes

Select this component when a robust standard recovery rectifier is required for 600V applications. The DO-15 package offers sufficient thermal mass for moderate current loads. Consider the 1.5 us reverse recovery time for frequency limitations in switching applications. Verify that the 50 A surge rating meets transient protection needs in the target circuit design.

Part Context

This part belongs to the 1N539x series of silicon rectifiers, which are widely used in general-purpose electronics. The series covers various voltage ratings from 50V to 1000V while maintaining a consistent 1.5A current capacity. The 1N5397 variant specifically targets 600V isolation requirements, balancing performance and cost for industrial and consumer applications.

Replacement Considerations

Direct substitutes include Vishay 1N5397GP-E3/54 and Diotec 1N5397. Verify pinout compatibility and thermal derating curves before substitution. Ensure replacement parts meet the same reverse voltage and current ratings.
