BY399P-E3/54

Overview

The BY399P-E3/54 is a single silicon rectifier diode from the Vishay BY399P series, housed in a DO-201AD axial through-hole package. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current of 3 A. The device exhibits a maximum non-repetitive peak forward surge current of 100 A and a typical reverse recovery time of 0.5 µs. Forward voltage drop is limited to 1.25 V at rated current, with leakage current capped at 10 µA. Operating junction temperature ranges up to 125 °C.

Feature Summary

• Fast switching capability designed for high-efficiency power supply applications
• Low forward voltage drop to minimize conduction losses
• Low leakage current characteristics for improved circuit stability
• High forward surge current handling capability

Applications

• Fast switching rectification in power supplies
• General-purpose rectification circuits
• Efficiency-critical electronic systems

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status via the E3 suffix documentation. Ensure the DO-201AD package dimensions match design requirements. Validate electrical parameters such as reverse voltage and current ratings against specific application needs before integration.

Selection Notes

Select this component for applications requiring fast recovery times and moderate current handling in through-hole designs. Compare performance metrics like reverse recovery time and forward voltage against alternative rectifiers. Ensure thermal management supports the specified maximum junction temperature limit during operation.

Part Context

This part belongs to the BY396P through BY399P family of soft recovery fast-switching plastic rectifiers manufactured by Vishay General Semiconductor. These devices share common mechanical features including molded epoxy bodies meeting UL-94V-0 flammability ratings and matte tin-plated terminals suitable for standard soldering processes.

Replacement Considerations

Direct substitutes within the same series include BY396P, BY397P, and BY398P, which offer varying reverse voltage ratings while maintaining identical current and package specifications. Verify voltage derating requirements when selecting lower-rated alternatives.
