BA157GPHE3/73

Overview

The BA157GPHE3/73 is a standard single diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average rectified current (Io) of 1 A. The device utilizes the SUPERECTIFIER series technology, offering fast recovery characteristics with a reverse recovery time (trr) of less than or equal to 500 ns for currents greater than 200 mA. It is housed in a DO-204AL (DO-41) axial through-hole package and operates within a junction temperature range of -65°C to 125°C.

Feature Summary

Fast recovery performance suitable for high-speed switching applications
High surge current capability inherent to the DO-41 axial package design
Compliant with RoHS 3 standards for environmental safety

Applications

General purpose rectification in power supplies
Freewheeling diodes in inductive load circuits
Protection against reverse polarity in DC circuits

Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by Vishay. Verification of availability should focus on existing stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific revision and packaging condition, as original manufacturer support and new production runs are unavailable. Cross-referencing with direct substitute part numbers is recommended for ongoing designs.

Selection Notes

Select this component only for legacy system maintenance or repair where exact form-factor compatibility is required. For new designs, consider active alternatives within the Vishay BA157 series or equivalent fast recovery diodes from other manufacturers. Ensure that the selected replacement matches the 400V Vr and 1A Io ratings while verifying thermal management requirements for the DO-41 package.

Part Context

The BA157GPHE3/73 belongs to Vishay's SUPERECTIFIER series, which emphasizes fast recovery times for efficient power conversion. The 'E3' suffix indicates lead-free termination compliant with RoHS directives, while '/73' denotes the Tape & Box (TB) packaging format. This specific variant represents a discontinued iteration of the widely used BA157 standard diode line.
