BY397P-E3/54

Overview

The BY397P-E3/54 is a standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 200 V. The device utilizes a DO-201AD axial through-hole package. Key electrical characteristics include a forward voltage of 1.1 V at 3 A, a reverse leakage current of 5 µA at 200 V, and a reverse recovery time of 3 µs. The component operates within a junction temperature range of -65°C to 175°C.

Feature Summary

Standard recovery performance with 3 µs reverse recovery time for general-purpose applications
High thermal stability supporting junction temperatures up to 175°C
Low forward voltage drop of 1.1 V at rated current for efficiency
Robust construction in DO-201AD axial package for through-hole mounting

Applications

General purpose rectification in power supplies
Freewheeling diodes in inductive load circuits
DC power conversion systems

Procurement Notes

Verify the specific suffix /54 corresponds to reel packaging when ordering. Confirm RoHS compliance status via the latest manufacturer datasheet as product specifications may evolve. Ensure the supplier provides official documentation matching the exact part number to avoid substitution errors with similar Vishay rectifiers.

Selection Notes

Select this component for circuits requiring 200 V blocking capability and 3 A continuous current handling. The 3 µs reverse recovery time suits standard frequency applications rather than high-frequency switching. Verify that the DO-201AD package dimensions fit the target PCB layout and that the thermal management supports the specified operating temperature range.

Part Context

This part belongs to the Vishay SUPERECTIFIER series, designed for robust general-purpose rectification. The BY397P variant specifically addresses 200 V applications within the broader BY3xxP family. It complements other Vishay rectifiers offering different voltage ratings while maintaining consistent 3 A current capacity and package form factor.
