1N4947GP-E3/54

Overview

The Vishay 1N4947GP-E3/54 is a glass-passivated junction fast switching plastic rectifier in the Superectifier series. It features a maximum repetitive peak reverse voltage of 800 V and supports a maximum average forward rectified current of 1.0 A at 55 °C ambient temperature. The device exhibits a maximum instantaneous forward voltage of 1.3 V, a peak forward surge current capability of 25 A, and a typical maximum reverse recovery time of 500 ns. Operating within a junction and storage temperature range of -65 to +175 °C, it utilizes a DO-41 (DO-204AL) axial through-hole package.

Feature Summary

• Features a cavity-free glass-passivated junction for high reliability
• Utilizes Superectifier structure designed for high efficiency fast switching
• Provides high forward surge current capability with low leakage current

Applications

• Fast switching rectification in power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Telecommunication equipment applications

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 1N4947GP-E3/54 against official Vishay documentation. Confirm RoHS compliance status and E3 suffix adherence to JESD 201 class 1A whisker test requirements. Ensure procurement channels provide valid datasheet references to validate technical specifications prior to integration.

Selection Notes

Select this component for designs requiring an 800 V blocking voltage and 1.0 A continuous current handling in a standard axial package. Evaluate thermal derating curves for operation above 55 °C ambient temperatures. Consider the 500 ns reverse recovery time suitability for specific frequency requirements compared to faster alternatives in the same series.

Part Context

This component belongs to the Vishay 1N494xGP series, which includes variants rated from 200 V to 1000 V reverse voltage. All members share identical mechanical dimensions, current ratings, and packaging formats while differing primarily in their breakdown voltage thresholds. The series represents a standardized solution for general-purpose high-voltage rectification tasks.

Replacement Considerations

Compatible substitutes include other 800 V, 1 A fast recovery rectifiers in the DO-41 package. Verify electrical parameters such as reverse recovery time and forward voltage drop match application constraints before substitution.
