BY251GP-E3/54

Overview

The BY251GP-E3/54 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 3 A. The device utilizes a DO-201AD axial through-hole package. Key electrical parameters include a maximum DC reverse voltage of 50 V, a forward voltage of 1.1 V at 3 A, and a reverse leakage current of 5 µA at 50 V. The junction temperature range spans from -65°C to +175°C.

Feature Summary

• Glass-passivated silicon p-n junction construction for enhanced reliability
• High surge current capability designed for robust operation
• Compliant with RoHS directive and free from halogen-based substances

Applications

• General-purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching applications
• DC output rectification in low-voltage power converters

Procurement Notes

Verify the specific part number suffix against official Vishay documentation to confirm package type and compliance status. Confirm availability as distribution statuses change frequently. Ensure the component meets the required thermal and electrical specifications for the target application environment before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring a 50 V rating with 3 A continuous current handling in a through-hole format. Compare the 1.1 V forward voltage drop against system efficiency requirements. Verify that the DO-201AD package dimensions fit the PCB layout constraints and that the junction temperature rating supports the operating environment.

Part Context

This component belongs to the SUPERECTIFIER series, which emphasizes high reliability and ruggedness. The BY251 variant specifically targets low-voltage, high-current rectification needs within the broader family of glass-passivated rectifiers offered by Vishay for industrial and consumer electronics markets.

Replacement Considerations

Check for direct cross-references such as BY251G or equivalent Vishay parts with identical electrical ratings and pinout configurations. Ensure any substitute maintains the same DO-201AD package and RoHS compliance status.
