BYG20DHM3_A/I

Overview

The BYG20DHM3_A/I is a surface-mount avalanche-rated fast recovery rectifier from Vishay General Semiconductor. It features a 200 V maximum repetitive reverse voltage and a 1.5 A average forward current rating. The device utilizes glass passivation for environmental protection and is housed in the DO-214AC (SMB) package. Key electrical characteristics include a maximum reverse recovery time of 75 ns and an avalanche energy capability, making it suitable for high-reliability applications requiring robust switching performance.

Feature Summary

• Avalanche rated for rugged operation
• Fast recovery switching with low reverse recovery time
• Glass passivated junction for durability

Applications

• High-frequency power supply circuits
• Inductive load switching
• Free-wheeling diode applications

Procurement Notes

Verify the specific suffix 'A/I' against official Vishay documentation to confirm tape-and-reel packaging and lead-free compliance status. Ensure the component matches the DO-214AC footprint requirements for your PCB design. Cross-reference the datasheet revision date to confirm technical specifications have not changed.

Selection Notes

Select this component when avalanche capability is required alongside fast recovery characteristics. The 1.5 A current rating and 200 V blocking voltage define its operational limits. Consider the SMB package size for space-constrained designs compared to larger through-hole alternatives.

Part Context

This part belongs to the BYG series of fast recovery rectifiers. The 'HM3' designation indicates a halogen-free and RoHS-compliant variant. The 'A/I' suffix typically denotes specific packaging or marking configurations within Vishay's standard product line.

Replacement Considerations

Direct substitutes must match the 200 V, 1.5 A, DO-214AC form factor and avalanche rating. Verify pinout compatibility and thermal characteristics before substitution.
