BY255GPHE3/73

Overview

The BY255GPHE3/73 is a standard recovery rectifier diode from Vishay General Semiconductor, part of the SUPERECTIFIER series. It features a maximum repetitive peak reverse voltage of 1300 V and an average forward rectified current of 3 A. The device utilizes a glass-passivated junction within a DO-201AD axial package for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5 µA at 1300 V, a forward voltage drop of 1.1 V at 3 A, and a reverse recovery time of 3 µs. It operates with a junction temperature range of -65°C to 175°C.

Feature Summary

• Glass-passivated junction structure designed for high reliability applications
• SUPERECTIFIER construction providing low forward voltage drop and low leakage current
• Capable of handling high surge currents with robust thermal stability

Applications

• High voltage power supply circuits
• Industrial motor drive rectification
• General purpose rectification in demanding environments

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status as indicated by the E3 suffix. Ensure the DO-201AD axial lead form factor matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a high-voltage standard recovery diode is required for through-hole assembly. The 1300 V rating suits high-line applications, while the 3 A current capacity supports moderate power loads. Consider the 3 µs reverse recovery time for general frequency operation rather than high-speed switching scenarios.

Part Context

This part belongs to the Vishay SUPERECTIFIER family, which emphasizes reliability through glass passivation. The BY255 variant specifically addresses high-voltage needs within the broader BY series lineup. The HE3 designation indicates enhanced environmental compliance compared to earlier iterations.

Replacement Considerations

Cross-reference with other Vishay BY255GP variants such as BY255GP-E3/54 for different packaging options like tape and reel. Verify that substitute parts maintain identical voltage, current, and package specifications.
