BA157-E3/54

Overview

The BA157-E3/54 is a single silicon junction rectifier from the Vishay BA157 series, designed for through-hole mounting in DO-204AL packages. It features a maximum repetitive peak reverse voltage of 400 V and an average forward current rating of 1 A. The device exhibits a maximum forward voltage of 1.3 V at rated current and a peak non-repetitive forward surge current capacity of 20 A. Its peak reverse recovery time is specified at 150 ns. Operating temperatures range from -65°C to +125°C.

Feature Summary

Utilizes silicon junction technology for standard rectification applications
Provides high surge current handling capability via robust internal construction
Ensures reliable operation across extended industrial temperature ranges

Applications

General-purpose rectification in power supply circuits
Protection against reverse polarity in DC systems
Freewheeling diode applications in inductive load switching

Procurement Notes

Verify the complete part number including suffixes such as /54 to confirm specific packaging configurations like tape and reel quantities. Confirm RoHS compliance status directly with manufacturer documentation, as environmental declarations can vary by production batch or regional regulatory requirements. Ensure the ordering quantity matches the required reel specifications for automated assembly processes.

Selection Notes

Select this component when a 400 V blocking voltage and 1 A continuous current are required in a standard axial leaded package. Consider the 150 ns reverse recovery time for frequency limitations in switching applications. Compare against higher voltage variants like the BA158 if system transients exceed 400 V ratings.

Part Context

This component belongs to the Vishay BA157 series of general-purpose silicon rectifiers. These devices are engineered for cost-effective solutions in consumer electronics and industrial equipment where moderate voltage and current ratings are sufficient. The series offers standardized electrical characteristics compatible with widespread PCB layouts utilizing DO-204AL footprints.
