BYM12-50HE3/97

Overview

The BYM12-50HE3/97 is a surface-mount ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes Superectifier technology with a cavity-free glass-passivated junction in a GL41 (DO-213AB) package. The device features a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 50 V. Key electrical characteristics include an ultrafast reverse recovery time of 50 ns, a maximum instantaneous forward voltage of 1.0 V at 1.0 A, and a peak forward surge current capability of 30 A. It operates within a junction temperature range of -65 to +175 °C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging quantity and delivery mode. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure the component meets MSL level 1 specifications for your assembly process. Validate that the GL41 package dimensions match your PCB footprint requirements.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and low reverse recovery times. Consider the 50 V rating for low-voltage DC-DC conversion or freewheeling paths. Evaluate thermal management needs based on the specified thermal resistance values. Ensure the operating environment stays within the -65 to +175 °C junction temperature limits.

Part Context

This part belongs to the BYM12 series of surface-mount ultrafast rectifiers from Vishay. It shares the same physical package and general structural features as other variants in the family, differing primarily in voltage ratings. The HE3 designation indicates lead-free construction compliant with RoHS directives. The /97 suffix typically denotes reel packaging quantities.

Replacement Considerations

Direct replacements within the same series include BYM12-100HE3/97, BYM12-150HE3/97, BYM12-200HE3/97, BYM12-300HE3/97, and BYM12-400HE3/97. These alternatives offer higher voltage ratings while maintaining identical current and package specifications. Verify that the higher voltage rating does not negatively impact circuit performance.
