1N4947GPHE3/73

Overview

The Vishay 1N4947GPHE3/73 is a glass-passivated junction fast switching plastic rectifier designed for high reliability. It features a Superectifier structure and cavity-free construction to ensure low leakage current and high forward surge capability. The device operates with a maximum average forward rectified current of 1.0 A at 55 °C and withstands a maximum repetitive peak reverse voltage of 800 V. It supports a peak forward surge current of 25 A and maintains an operating junction temperature range from -65 °C to +175 °C.

Feature Summary

Superectifier structure for high reliability condition
Cavity-free glass-passivated junction
Fast switching for high efficiency
Low leakage current

Applications

Fast switching rectification of power supply
Inverters and converters
Freewheeling diodes for consumer applications
Telecommunication equipment

Procurement Notes

Verify the component against the official Vishay datasheet (Document Number: 88511) to confirm electrical parameters, specifically the 800 V reverse voltage rating and 1.0 A forward current. Ensure the package matches DO-41 (DO-204AL) and check RoHS compliance status via the E3 suffix confirmation. Confirm availability as this specific part number may be subject to discontinuation or lifecycle changes.

Selection Notes

Select this component for circuits requiring fast recovery characteristics and high surge current handling in axial leaded packages. It is suitable for applications demanding low leakage current and high thermal stability up to 175 °C. Verify that the 800 V blocking voltage aligns with the circuit's peak reverse voltage requirements and that the 1.0 A continuous current rating meets the load specifications.

Part Context

This component belongs to the 1N494xGP 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 200 V to 1000 V. The 1N4947GP variant specifically provides an 800 V rating within this lineup.

Replacement Considerations

Compatible substitutes include other 1N494xGP series parts from Vishay with matching voltage and current ratings, such as 1N4946GP or 1N4948GP, provided their specific reverse voltage ratings suit the application. Cross-manufacturer equivalents in the DO-41 package should be verified for identical electrical characteristics.
