BYG21MH

Overview

The BYG21MH is a fast recovery rectifier manufactured by Taiwan Semiconductor. It features a 1.5 A average rectified forward current and a 1000 V maximum repetitive peak reverse voltage. The device exhibits a typical reverse recovery time of 120 ns. It is housed in the DO-214AC (SMA) surface-mount package. The component is qualified to AEC-Q101 standards for automotive applications.

Feature Summary

• Glass passivated junction chip for reliability
• Fast switching characteristics for high efficiency
• High surge current capability

Applications

• Automotive electronics systems
• General purpose rectification
• High frequency switching circuits

Procurement Notes

Verify the specific suffix configuration when ordering, as variations exist within the product family. Confirm the active status directly with the manufacturer or authorized distributors, as supply availability may vary. Ensure the selected variant meets the required AEC-Q101 qualification if used in automotive contexts.

Selection Notes

Select this component for designs requiring a 1000 V blocking voltage with a 1.5 A current rating in a compact SMA package. The 120 ns recovery time makes it suitable for general-purpose fast recovery applications. Verify thermal management requirements based on the specific circuit load conditions.

Part Context

This part belongs to the BYG series of surface mount fast recovery rectifiers from Taiwan Semiconductor. The series offers various voltage ratings up to 1000 V in the DO-214AC package. The 'H' suffix typically denotes AEC-Q101 qualification, distinguishing it from standard industrial variants.

Replacement Considerations

Check for direct substitutes such as BYG21MHR2G or BYG21MHF3G which share similar electrical specifications. Ensure pinout compatibility and package dimensions match before substitution.
