BYM12-300HE3/97

Overview

The BYM12-300HE3/97 is a surface-mount ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the Superectifier structure and features a cavity-free glass-passivated junction in 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 300 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.25 V, a maximum reverse recovery time of 50 ns, and a peak forward surge current capability of 30 A. The component operates within a junction temperature range of -65 to +175 °C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the delivery mode and base quantity. The EGL41D-E3/97 variant corresponds to a 13-inch diameter plastic tape and reel with a base quantity of 5000 units. Confirm that the E3 suffix meets JESD 201 class 1A whisker test requirements if applicable to your assembly process. Ensure compliance with RoHS standards as indicated by the commercial grade designation.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery times. The 300 V rating makes it suitable for medium-voltage DC-DC conversion or AC-DC rectification stages. Consider the thermal resistance values provided in the datasheet for heat dissipation planning. The DO-213AB package allows for automated placement, which is beneficial for high-volume manufacturing processes requiring consistent alignment and soldering quality.

Part Context

This part belongs to the BYM12-xxx series, also identified as EGL41x, representing Vishay's ultrafast rectifier lineup. The 'EGL41D' code specifically denotes the 300 V voltage rating within this family. These devices are designed to replace standard recovery diodes in applications where efficiency and speed are critical. The series encompasses various voltage ratings from 50 V to 400 V, sharing common mechanical and thermal characteristics while differing in blocking voltage capabilities.

Replacement Considerations

Direct substitutes within the same voltage and current ratings include other BYM12-300 variants with different packaging options such as BYM12-300HE3/96. Cross-referencing with EGL41F-E3 parts is necessary only if the voltage rating differs. Verify pinout compatibility and thermal performance metrics before substituting with components from other manufacturers.
