BYM12-400HE3/96

Overview

The BYM12-400HE3/96 is a surface-mount ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes Superectifier structure technology and features a cavity-free glass-passivated junction within a GL41 (DO-213AB) package. The device supports a maximum average forward rectified current of 1.0 A at 75 °C and withstands a maximum repetitive peak reverse voltage of 400 V. Key electrical parameters include a maximum instantaneous forward voltage of 1.25 V, a peak forward surge current capability of 30 A, and an ultrafast maximum reverse recovery time of 50 ns. The component operates across a junction temperature range of -65 to +175 °C.

Procurement Notes

Verify the specific part number against official Vishay documentation to confirm compliance with RoHS directives and material categorization standards. Ensure that the EGL41G variant designation matches the required 400 V rating. Confirm packaging specifications align with automated placement requirements and moisture sensitivity level classifications before procurement.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and high thermal stability. The 400 V reverse voltage rating suits applications involving higher voltage transients. Verify that the operating environment remains within the specified -65 to +175 °C junction temperature range. Consider the DO-213AB package dimensions for board layout constraints and ensure adequate copper pad sizing for optimal thermal dissipation.

Part Context

This device belongs to the BYM12 series of surface-mount ultrafast rectifiers from Vishay. The series encompasses multiple voltage ratings ranging from 50 V to 400 V, all sharing identical physical packages and general structural features. The BYM12-400HE3/96 specifically represents the highest voltage option within this standard lineup, utilizing the EGL41G suffix code.

Replacement Considerations

Direct substitutes within the same family include BYM12-xxx variants with different voltage ratings if circuit requirements allow. Cross-referencing with other Vishay Superectifier products requires verification of matching reverse recovery times and forward voltage characteristics.
