BY252GP-E3/54

Overview

The BY252GP-E3/54 is a silicon rectifier diode from Vishay General Semiconductor, designed for general-purpose applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 3 A. The device utilizes a standard recovery technology with a typical reverse recovery time of 3 µs. It is housed in a DO-201AD axial through-hole package. Key electrical characteristics include a forward voltage of 1.1 V at 3 A and a low reverse leakage current of 5 µA at the rated voltage.

Feature Summary

• High-voltage capability with a 400 V DC reverse voltage rating
• Robust 3 A average forward current handling
• Low leakage current specification for improved efficiency
• Standard recovery speed suitable for general power conversion

Applications

• General purpose rectification circuits
• Power supply input stages
• Freewheeling diode applications
• Industrial control systems

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 package dimensions match your PCB footprint requirements. Validate that the standard recovery time aligns with your circuit's switching frequency constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 400 V blocking voltage and 3 A continuous current are required in an axial leaded package. Consider the 3 µs reverse recovery time for compatibility with lower-frequency switching applications. Compare thermal performance and forward voltage drop against alternative packages if space constraints exist. Ensure operating junction temperature ranges meet environmental conditions.

Part Context

This part belongs to the SUPERECTIFIER series, which emphasizes reliability in surface mount and through-hole technologies. The BY252 variant specifically addresses mid-range voltage requirements within the broader BY2xxGP family. It serves as a standard replacement for legacy rectifiers requiring similar electrical ratings in industrial and consumer electronics designs.

Replacement Considerations

Direct substitutes must match the 400 V, 3 A, DO-201AD specifications. Verify equivalent reverse recovery times and forward voltage characteristics. Cross-reference pinout configurations to ensure mechanical compatibility. Check for updated RoHS directives if replacing older inventory.
