BYM07-50HE3/98

Overview

The BYM07-50HE3/98 is a surface-mount glass-passivated ultrafast rectifier manufactured by Vishay General Semiconductor. It features a Superectifier structure and cavity-free junction within a GL34 (DO-213AA) package. Key electrical ratings include a maximum average forward rectified current of 0.5 A, a maximum repetitive peak reverse voltage of 50 V, and a peak forward surge current of 10 A. The device exhibits an ultrafast reverse recovery time of 50 ns and a maximum instantaneous forward voltage of 1.25 V at 0.5 A. Operating temperatures range from -65 °C to +175 °C.

Procurement Notes

Verify the specific part number against official Vishay documentation to confirm compliance with RoHS standards and material categorization requirements. Ensure that the GL34 package dimensions and polarity band markings align with design specifications. Confirm thermal resistance parameters match the intended PCB copper pad layout for adequate heat dissipation during operation.

Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge. The 50 V rating suits low-voltage DC-DC conversion stages. Verify that the 0.5 A continuous current capability meets the load requirements. Consider the operating temperature range when designing for extreme environmental conditions or high ambient temperatures.

Part Context

This device belongs to the BYM07-xxx series of surface-mount ultrafast rectifiers. It shares the same physical package and general characteristics as other variants in the series, differentiated primarily by their repetitive peak reverse voltage ratings ranging from 50 V to 400 V. The EGL34x designation corresponds to the specific voltage rating within this product family.

Replacement Considerations

Direct substitutes within the same series include BYM07-100HE3/98, BYM07-150HE3/98, BYM07-200HE3/98, BYM07-300HE3/98, and BYM07-400HE3/98. These parts share identical current, speed, and package specifications but offer higher voltage blocking capabilities.
