BY251GP-E3/73

Overview

The BY251GP-E3/73 is a standard recovery rectifier 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 exhibits a maximum non-repetitive peak forward surge current of 80 A at 8.3 ms single half-sine-wave. Forward voltage drop is specified at 1.1 V when conducting 3 A, while reverse leakage current remains limited to 5 µA at the rated 50 V. The component utilizes a DO-201AD axial through-hole package and supports junction temperatures ranging from -65 °C to +175 °C.

Feature Summary

• Glass-passivated junction structure for enhanced reliability
• High thermal stability with extended operating temperature range
• Low forward voltage drop for improved efficiency

Applications

• General-purpose rectification in power supplies
• Bridge rectifiers for AC-to-DC conversion
• Free-wheeling diodes in inductive load circuits

Procurement Notes

Verify the specific suffix E3/73 against the official Vishay datasheet to confirm RoHS compliance and ammo pack packaging. Ensure the DO-201AD lead form matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring robust high-current handling with moderate reverse voltage ratings. The wide junction temperature range makes it suitable for environments with significant thermal fluctuations where standard silicon diodes might fail prematurely.

Part Context

This part belongs to the SuperEctifier series, characterized by cavity-free glass-passivated junctions designed for high reliability.
