• Optimized for surface-mount assembly using the compact TO-277A package format
• Capable of sustained operation across an extended industrial temperature spectrum

Applications

• General-purpose rectification in power supply circuits
• Protection stages in automotive electronic systems
• Industrial equipment requiring reliable AC-to-DC conversion

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required avalanche characteristics and package variant. Ensure compliance with relevant environmental directives prior to integration into final assemblies.

Selection Notes

Select this component when avalanche capability is required alongside standard rectification functions. The TO-277A package offers space efficiency compared to through-hole alternatives while maintaining adequate thermal performance for moderate current loads.

Part Context

This part belongs to Vishay's discrete diode portfolio, specifically within the avalanche rectifier category. It complements standard recovery devices by providing additional resilience against reverse breakdown conditions without compromising forward conduction efficiency.

Replacement Considerations

Consult official substitution lists for equivalent avalanche-rated rectifiers in compatible packages. Verify electrical parameters match before replacing existing designs.
