Procurement Notes
Verify that the ordering suffix E3 confirms RoHS compliance and JESD 201 class 1A whisker test adherence. Confirm the /73 designation corresponds to the specified ammo pack delivery mode. Ensure the component matches the exact 1N4948GP electrical ratings before integration into designs.
Selection Notes
Select this component when a 1000 V rating is required alongside fast switching performance. The Superectifier structure provides enhanced reliability compared to standard rectifiers. Verify thermal management requirements against the specified junction temperature limits and derating curves for the target ambient conditions.
Part Context
This part belongs to the Vishay 1N494xGP family of glass passivated fast switching rectifiers. The datasheet explicitly states these components are not recommended for new designs. The GP suffix indicates the specific Superectifier construction within the broader Vishay diode portfolio.
Replacement Considerations
Cross-reference with other 1N4948 variants or equivalent 1000 V fast recovery rectifiers if availability is constrained. Verify pinout compatibility and thermal resistance parameters match the original design specifications.
