BY255GP-E3/73

Overview

The BY255GP-E3/73 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 1300 V and an average forward rectified current of 3 A. The device exhibits a maximum forward voltage of 1.1 V at 3 A and a reverse leakage current of 5 µA at 1300 V. Key electrical characteristics include a reverse recovery time of 3 µs and a junction capacitance of 40 pF at 4 V and 1 MHz. It operates within a junction temperature range of -65°C to 175°C.

Feature Summary

• Glass passivated junction construction for enhanced environmental stability and reliability under various operating conditions.
• High surge overload capability designed to withstand transient current events during power-up or fault conditions.
• Utilizes metal oxide varistor technology principles inherent to the SUPERECTIFIER series for robust performance.

Applications

• General purpose rectification in industrial power supplies
• Inverter circuits requiring high voltage blocking capabilities
• DC-DC converter stages with standard recovery requirements

Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS3 compliance status and check for specific manufacturing date codes if long-term supply continuity is required. Review product change notifications for any potential parameter shifts in legacy stock.

Selection Notes

Select this component when a 1300 V rating and 3 A continuous current are necessary. Ensure the application does not require faster switching speeds, as the 3 µs reverse recovery time limits high-frequency efficiency. Verify that the DO-201AD axial package fits the PCB layout constraints.

Part Context

This diode belongs to the SUPERECTIFIER series, which emphasizes high reliability and ruggedness. It is part of a broader family of glass-passivated rectifiers offering various voltage ratings from 50 V to 1000 V+, designed for general-purpose applications where cost-effectiveness and durability are prioritized over ultra-fast switching.

Replacement Considerations

Check for direct substitutes such as BY255GPHE3/73, which shares identical electrical specifications but differs in packaging (tape and reel vs. ammo pack). Other equivalent parts must match the 1300 V, 3 A, and 3 µs trr parameters strictly.
