Overview
The BYG22DHM3_A/I is an ultrafast avalanche SMD rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and operates in the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 200 V, an average forward current of 2.0 A, and a peak forward surge current of 35 A. Key electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 2.0 A, a maximum reverse current of 1.0 μA, and an ultra-fast reverse recovery time of 25 ns. It is qualified to AEC-Q101 standards.
Feature Summary
- Ultrafast reverse recovery time with soft recovery characteristic
- Controlled avalanche characteristic for pulse energy handling
- Glass passivated pellet chip junction for reliability
- Halogen-free, RoHS-compliant construction
Applications
- High frequency rectification in switching mode converters
- Freewheeling applications in inverters
- Automotive electronic systems
- Telecommunication equipment power supplies
Procurement Notes
Verify that the ordering suffix HM3 confirms halogen-free compliance and AEC-Q101 qualification status. Confirm the delivery mode matches the required base quantity for the specific reel size. Ensure the component marking code aligns with the specified 200 V rating variant within the BYG22D series.
Selection Notes
Select this component when high-frequency switching performance and avalanche ruggedness are required in a compact surface-mount form factor. The SMA package facilitates automated placement. Verify thermal resistance requirements against the application's ambient temperature and mounting pad layout constraints.
Part Context
This part belongs to the BYG22 series of ultrafast avalanche rectifiers from Vishay. The series includes variants with different reverse voltage ratings (50 V, 100 V, 200 V). The BYG22D specifically denotes the 200 V version. The HM3 suffix indicates a halogen-free, RoHS-compliant product that meets automotive reliability standards.
Replacement Considerations
Direct substitutes within the same family include BYG22DHM3_A/H, which shares identical electrical specifications but differs in packaging configuration.
