BYG20GHM3_A/I

Overview

The BYG20GHM3_A/I is an ultrafast avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 1.5 A per diode. The device utilizes the FRED Pt technology, achieving a typical reverse recovery time (trr) of 75 ns. Forward voltage (Vf) is specified at 1.4 V when tested at 1.5 A. The component operates within a junction temperature range of -55°C to 150°C and is housed in a surface-mount DO-214AC (SMA) package.

Feature Summary

• Incorporates FRED Pt technology for optimized switching performance
• Engineered with avalanche capability for robust operation
• Designed as an ultrafast rectifier for high-frequency applications

Applications

• High-frequency power supply circuits
• Ultrafast rectification in consumer electronics
• General purpose fast recovery applications requiring avalanche ruggedness

Procurement Notes

Verify the specific suffix _A/I against official Vishay documentation to confirm tape and reel configuration or marking variations. Ensure compatibility with standard SMA footprint dimensions during PCB layout. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by end-product regulations.

Selection Notes

Select this component for designs requiring fast recovery characteristics combined with avalanche energy rating. The 1.5 A current rating suits moderate power applications where size constraints favor surface mount packages. Compare the 75 ns reverse recovery time against circuit switching frequencies to ensure minimal switching losses. Evaluate thermal management requirements given the 150°C maximum junction temperature limit.

Part Context

This part belongs to the BYG series of ultrafast rectifiers from Vishay. The 'E3' or 'M3' suffixes typically denote lead-free and halogen-free compliant versions, while '_A/I' indicates specific packaging or marking attributes defined by the manufacturer. It shares the core electrical specifications with other variants in the BYG20 family but may differ in physical handling or identification markings.

Replacement Considerations

Direct substitutes include BYG20G-E3/TR3 and BYG20GHM3/TR, which share identical 400V/1.5A ratings and DO-214AC packaging. Verify that replacement parts maintain the same avalanche capability and reverse recovery time specifications to ensure circuit performance parity.
