BYM07-300HE3_B/H

Overview

The BYM07-300HE3_B/H is a silicon planar fast recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current of 500 mA. The device utilizes a GL34 (DO-213AA) surface-mount MELF package. Key electrical characteristics include a maximum DC reverse leakage current of 5 µA at rated voltage and a typical forward voltage drop of 1.1 V at 500 mA. The component is designed for high-frequency applications with a maximum reverse recovery time of 50 ns.

Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• Surface-mount MELF construction for automated assembly
• High surge current capability for transient protection

Applications

• High frequency rectification in switching mode power supplies
• Freewheeling diodes in inverters and converters
• Automotive electronic circuits requiring robust rectification

Procurement Notes

Verify the specific suffix B/H against the official datasheet to confirm it denotes the standard commercial grade variant rather than automotive or specialized reliability grades. Ensure the ordering part number matches the exact package style and marking requirements specified in the manufacturer's documentation before finalizing procurement.

Selection Notes

Select this component when a 300 V reverse voltage rating and 500 mA continuous current are required in a compact surface-mount form factor. The 50 ns reverse recovery time makes it appropriate for frequencies where standard rectifiers would exhibit excessive losses. Compare thermal resistance values if operating near maximum current limits.

Part Context

This part belongs to the BYM07 series of ultrafast recovery diodes from Vishay. These devices are engineered for efficiency in high-speed switching environments. The series offers various voltage ratings within the same mechanical package, allowing designers to standardize on footprint while adjusting voltage specifications for different circuit requirements.

Replacement Considerations

Check for direct substitutes such as the BYM07-300-E3/83 or BYM07-300HE3_A/H, ensuring pinout compatibility and identical electrical parameters. Verify that any replacement maintains the same GL34 package dimensions and thermal characteristics to fit existing board layouts.
