BYM12-300-E3/97

Overview

The BYM12-300-E3/97 is a surface-mount ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a Superectifier structure with a cavity-free glass-passivated junction in the GL41 (DO-213AB) package. The device provides a maximum average forward rectified current of 1.0 A and a peak forward surge current of 30 A. It has a maximum repetitive peak reverse voltage of 300 V, a maximum DC blocking voltage of 300 V, and a maximum RMS voltage of 210 V. Electrical characteristics include a maximum instantaneous forward voltage of 1.25 V at 1.0 A, a maximum reverse recovery time of 50 ns, and a typical junction capacitance of 14 pF at 4.0 V and 1 MHz. Thermal resistance from junction to ambient is 60 °C/W, and the operating junction temperature range extends from -65 °C to +175 °C.

• Telecommunication infrastructure

Procurement Notes

Verify that the ordering suffix matches the required delivery mode, as the /97 designation indicates a specific reel quantity. Confirm RoHS compliance status through official documentation before procurement. Ensure the component meets MSL level 1 requirements for automated placement processes. Validate thermal management capabilities against the specified junction-to-ambient thermal resistance values for the target application environment.

Selection Notes

Select this component when a single ultrafast rectifier with a 300 V reverse voltage rating is required in a DO-213AB package. Consider the 50 ns reverse recovery time for high-frequency switching applications where low switching losses are critical. Evaluate the 1.0 A average forward current capability against the circuit's continuous load requirements. Verify that the operating junction temperature range of -65 °C to +175 °C aligns with the environmental conditions of the intended deployment.

Part Context

This part belongs to the BYM12-xxx series of surface-mount glass passivated ultrafast rectifiers. The series offers various voltage ratings ranging from 50 V to 400 V within the same GL41 package footprint. The EGL41x designation corresponds to specific voltage variants within this family. The E3 suffix denotes RoHS compliance, while the trailing numbers indicate the packaging configuration.

Replacement Considerations

Direct substitutes within the same series include BYM12-200-E3/97 and BYM12-400-E3/97, which share identical package dimensions and electrical characteristics except for their maximum repetitive peak reverse voltage ratings. Ensure the replacement part's voltage rating meets or exceeds the original circuit requirements.
