BYM12-400HE3/97

Overview

The BYM12-400HE3/97 is a surface-mount glass-passivated ultrafast rectifier manufactured by Vishay General Semiconductor. It features a Superectifier structure and operates in the 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 characteristics 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 is rated for operating junction and storage temperatures ranging from -65 °C to +175 °C.

Feature Summary

• Superectifier structure designed for high reliability under demanding conditions
• Cavity-free glass-passivated junction construction
• Ultrafast reverse recovery time with low switching losses
• High forward surge current capability

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in inverters
• Consumer electronics power supplies
• Computer equipment power systems
• Automotive electronic circuits
• Telecommunication infrastructure

Procurement Notes

Verify that the ordering suffix /97 corresponds to the 5000-unit base quantity delivered in 13-inch diameter plastic tape and reel packaging. Confirm RoHS compliance status associated with the E3 designation. Ensure the specific voltage rating matches the required circuit parameters before procurement.

Selection Notes

Select this component when a single-diode configuration with a 400 V blocking voltage is required. The DO-213AB package is suitable for automated placement processes. Consider the 50 ns reverse recovery time for high-frequency switching applications where low switching losses are critical. Validate thermal management requirements against the specified junction temperature limits.
