BYM07-400HE3/83

Overview

The BYM07-400HE3/83 is a surface-mount glass-passivated ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the Superectifier structure and GL34 (DO-213AA) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 400 V, a maximum average forward rectified current of 0.5 A at 75 °C, and a peak forward surge current of 10 A. The device features an ultrafast reverse recovery time of 50 ns, a maximum instantaneous forward voltage of 1.35 V at 0.5 A, and a typical junction capacitance of 7.0 pF. Operating temperatures range from -65 °C to +175 °C.

Feature Summary

• Superectifier structure for high reliability
• Cavity-free glass-passivated junction
• Ultrafast reverse recovery time
• Low switching losses and high efficiency

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 the specific ordering suffix /83 corresponds to the 9000-unit 13-inch tape and reel delivery mode as documented in the datasheet. Confirm that the EGL34G variant matches the required 400 V rating. Ensure compliance with RoHS standards and JESD 201 class 1A whisker test requirements are met for the intended assembly process.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery charge. The 400 V rating suits higher voltage DC-DC conversion stages. Consider the 0.5 A current limit and thermal resistance values for proper heat dissipation planning in compact surface-mount layouts.

Part Context

This part belongs to the BYM07 series of ultrafast rectifiers, which offers various voltage ratings from 50 V to 400 V. All variants share the same GL34 package and general electrical characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings indicated by color-coded bands on the component body.

Replacement Considerations

Direct substitutes within the same family include other BYM07 variants with different voltage ratings, such as BYM07-300 or BYM07-200, provided the circuit voltage requirements allow for lower breakdown voltages. Cross-brand replacements require matching the DO-213AA package, 0.5 A current rating, and ultrafast recovery specifications.
