BY251GPHE3/73

Overview

The BY251GPHE3/73 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 with a plastic encapsulation. Key electrical characteristics include a maximum DC reverse voltage of 1300 V, a typical forward voltage of 1.1 V at 3 A, and a reverse leakage current of 5 µA at 1300 V. The component operates within a junction temperature range of -65°C to 175°C and has a specified reverse recovery time of 3 µs.

Feature Summary

• High-reliability construction designed for robust power applications
• Standard recovery speed suitable for general-purpose rectification
• Halogen-free and RoHS compliant manufacturing process

Applications

• General-purpose rectification in power supplies
• Freewheeling diode circuits
• DC-to-AC conversion systems

Procurement Notes

Verify the specific suffix HE3/73 against official Vishay documentation to confirm halogen-free status and tape-and-reel packaging configuration. Confirm current availability status as product lifecycle changes may affect procurement channels. Ensure the DO-201AD axial lead form factor matches the target PCB layout requirements before finalizing orders.

Selection Notes

Select this component when a 3 A current rating and 50 V blocking capability are required for standard frequency rectification. The 3 µs reverse recovery time distinguishes it from ultra-fast variants, making it appropriate for lower-frequency applications. Verify that the DO-201AD package size fits the mechanical constraints of the design.

Part Context

This part belongs to the SUPERECTIFIER series, which focuses on high-reliability silicon planar p-n junction rectifiers. The GP designation indicates a specific grade within Vishay's standard recovery lineup. The E3 suffix denotes compliance with environmental directives regarding restricted substances.
