BY254GP-E3/54

Overview

The BY254GP-E3/54 is a single standard recovery rectifier diode manufactured by Vishay General Semiconductor. It features a maximum repetitive reverse voltage of 800 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 forward voltage of 1.1 V at 3 A, a reverse leakage current of 5 µA at 800 V, and a reverse recovery time of 3 µs. The component supports a non-repetitive peak forward surge current of 100 A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass-passivated junction structure for high reliability applications
• Cavity-free design utilizing Superectifier technology
• Low forward voltage drop and low leakage current characteristics

Applications

• General purpose rectification circuits
• Free wheeling diode applications
• High reliability power supply designs

Procurement Notes

Verify the specific suffix E3/54 to confirm lead-free RoHS compliance and reel packaging format. Confirm availability status as this component may be subject to discontinuation notices or production changes. Ensure the DO-201AD axial package matches the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when an 800 V blocking capability and 3 A continuous current rating are required in a through-hole configuration. The 3 µs reverse recovery time suits standard frequency applications rather than high-speed switching. Consider thermal management constraints given the 150°C maximum operating temperature limit and the thermal resistance inherent to the DO-201AD package.

Part Context

This part belongs to the BY25xGP series of glass-passivated silicon rectifiers from Vishay. The series offers voltage ratings ranging from 200 V to 1300 V while maintaining consistent 3 A current handling. The GP designation indicates the use of Superectifier technology, which provides superior reliability compared to standard plastic encapsulated diodes through its cavity-free glass-to-plastic junction passivation.

Replacement Considerations

Direct substitutes within the same Vishay lineup include BY253GP-E3/54 (600 V) and BY255GP-E3/54 (1300 V), provided voltage margins allow adjustment. Cross-manufacturer equivalents must match the 800 V Vr, 3 A Io, and DO-201AD package dimensions.
