Single Diodes Procurement Notes

Verify the specific suffix /91 against official documentation to confirm packaging details, as standard datasheets list /54 (Reel) and /73 (Ammo pack). Confirm RoHS compliance status and check for 'Not for New Designs' restrictions before finalizing procurement plans.

Single Diodes Selection Notes

Select this component for applications requiring 600 V reverse voltage and 1 A continuous current handling. Ensure the circuit design accommodates the 200 ns reverse recovery time and 1.2 V forward voltage drop. Verify thermal management requirements given the 175 °C maximum junction temperature rating.

Single Diodes Part Context

This part belongs to the 1N493xGP series of glass passivated junction fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V, all sharing similar mechanical and electrical characteristics.

Single Diodes Replacement Considerations

Compatible substitutes within the same family include 1N4933GP through 1N4936GP, provided their lower reverse voltage ratings meet the application requirements.
