BYM11-400HE3/97

Overview

The BYM11-400HE3/97 is a surface-mount glass passivated junction fast switching rectifier manufactured by Vishay General Semiconductor - Diodes Division. It belongs to the BYM11-xxx series and utilizes the GL41 (DO-213AB) package. The device features a maximum repetitive peak reverse voltage of 400 V, a maximum average forward rectified current of 1.0 A at 55 °C, and a peak forward surge current of 30 A. Its maximum instantaneous forward voltage is 1.3 V at 1.0 A, with a maximum reverse recovery time of 150 ns. The component operates within a junction and storage temperature range of -65 °C to +175 °C.

Procurement Notes

Verify that the ordering suffix /97 corresponds to the 13-inch diameter plastic tape and reel delivery mode with a base quantity of 5000 units. Confirm RoHS compliance and material categorization status through official Vishay documentation before procurement. Ensure the specific part number matches the required 400 V rating within the BYM11-xxx family.

Selection Notes

Select this component when a 400 V blocking voltage and 1.0 A continuous current are required in a compact DO-213AB footprint. Consider its 150 ns reverse recovery time for high-frequency switching applications. Evaluate thermal resistance parameters against the expected ambient temperature and load conditions to ensure operation remains within the specified 175 °C junction limit.

Part Context

This component is part of the BYM11-xxx Superectifier family from Vishay, which includes variants rated from 50 V to 1000 V. All members share the same GL41 (DO-213AB) surface-mount package and general electrical architecture. The BYM11-400 variant specifically addresses mid-range voltage requirements while maintaining the series' fast switching and low leakage attributes.

Replacement Considerations

Direct substitutes within the same Vishay family include BYM11-500HE3/97 and BYM11-600HE3/97, provided higher voltage ratings are acceptable. Cross-manufacturer replacements must match the DO-213AB outline, 1.0 A current rating, and 150 ns recovery time specifications.
