Procurement Notes
Verify the specific suffix 'E3/54' against official documentation to confirm RoHS compliance and reel packaging specifications. Ensure the component matches the exact Vishay General Semiconductor part number before procurement. Cross-reference datasheet revision dates to validate technical parameters.
Selection Notes
Select this component for applications requiring fast switching capabilities and low leakage current in standard through-hole configurations. Verify that the 400 V reverse voltage rating aligns with circuit requirements. Confirm thermal management strategies are adequate for the specified operating temperature range.
Part Context
This component belongs to the 1N494xGP series of Superectifier fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings, sharing common mechanical and electrical characteristics such as the DO-41 package and cavity-free glass passivation technology.
Replacement Considerations
Consult official Vishay documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers without validating electrical parameters and physical dimensions.
