Overview

The BYG20DHM3_A/H is a fast recovery rectifier from Vishay Semiconductors, designed for surface-mount applications in the DO-214AC (SMA) package. It features a single configuration with a maximum average forward current of 1.5 A and a repetitive peak reverse voltage of 200 V. The device exhibits a typical forward voltage of 1.25 V and a maximum reverse current of 1 µA. Its fast recovery time is specified at 140 ns, supporting high-frequency switching operations. The component withstands a maximum surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C. It holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Fast recovery characteristics optimized for high-frequency power conversion efficiency
• Glass passivated junction structure ensuring robust environmental stability
• Soft recovery profile to minimize electromagnetic interference during switching
• Automotive-grade qualification compliant with AEC-Q101 standards

Applications

• High-frequency DC/DC converter circuits
• Free-wheeling diodes in synchronous rectification topologies
• Polarity protection in automotive electronic systems
• Snubber circuits in switch-mode power supplies

Procurement Notes

Verify the complete part number including suffixes against official Vishay documentation to ensure correct voltage and speed ratings. Confirm AEC-Q101 certification requirements if deploying in automotive contexts. Check RoHS compliance status via the manufacturer's datasheet. Validate package dimensions against PCB footprint specifications prior to procurement.

Selection Notes

Select this component when a 200 V rating and 1.5 A continuous current capacity are required in an SMA package. Consider the 140 ns recovery time for applications demanding faster switching than standard rectifiers but less speed than ultra-fast types. Ensure thermal management supports the 150 °C maximum junction temperature limit in the intended operating environment.

Part Context

This device belongs to the BYG series of fast silicon mesa SMD rectifiers manufactured by Vishay Semiconductors. The series utilizes glass passivation technology for enhanced durability. The BYG20D variant represents the 200 V version within this family, sharing common packaging and general structural features with other voltage ratings in the same product line.

Replacement Considerations

Cross-reference with BYG20JHM3_A/H for higher voltage capability or ESH1DHM3_A/H for faster recovery performance. Verify pinout compatibility and thermal characteristics before substituting.
