Overview
The BYG20GHE3_A/I is a surface-mount avalanche fast recovery rectifier manufactured by Vishay General Semiconductor. It features a DO-214AC (SMA) package and supports an average forward current of 1.5 A with a maximum repetitive peak reverse voltage of 400 V. The device exhibits a typical reverse recovery time of 75 ns and a forward voltage of 1.4 V at 1.5 A. It operates within a junction temperature range of -55°C to +150°C and maintains a reverse leakage current of 1 µA at 400 V.
Feature Summary
- Incorporates avalanche technology for robust operation under transient conditions
- Utilizes glass-passivated junction structure for enhanced reliability
- Designed for high-speed switching applications with low reverse recovery characteristics
Applications
- High-frequency power supply circuits
- Free-wheeling diode implementations in DC-DC converters
- Snubber circuits requiring fast recovery performance
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and qualification status, as variations exist between tape-and-reel and cut-tape formats. Ensure compliance with RoHS directives and check for AEC-Q101 automotive qualification requirements if deploying in automotive environments. Cross-reference datasheet revisions to confirm parameter consistency.
Selection Notes
Select this component when a surface-mount fast recovery rectifier with avalanche capability is required for 400V applications. Compare its 75 ns reverse recovery time against standard rectifiers to ensure compatibility with high-frequency switching topologies. Evaluate the DO-214AC footprint constraints against available PCB real estate and thermal management needs for 1.5 A continuous current loads.
Part Context
This part belongs to the BYG20 series of fast recovery rectifiers from Vishay. It shares the same electrical specifications as the BYG20G-E3/TR3 but may differ in packaging or automotive qualification status. The series is designed for general-purpose high-efficiency rectification where fast switching and reliability are critical factors in circuit design.
