BYG22DHE3_A/H

Overview

The BYG22DHE3_A/H is an ultrafast avalanche rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 200 V and an average forward current of 2.0 A. It features a soft recovery characteristic with a maximum reverse recovery time of 25 ns and a low forward voltage of 1.1 V at 2.0 A. The device supports a peak forward surge current of 35 A and operates within a junction temperature range of -55 °C to +150 °C. Packaged in the SMA (DO-214AC) surface-mount format, it meets AEC-Q101 automotive qualification standards.

Feature Summary

• Avalanche-rated capability for energy dissipation during inductive load switching
• Glass passivated pellet chip junction for enhanced reliability

• Low profile package optimized for automated placement processes

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in consumer electronics
• Inverter circuits for computer systems
• Automotive electronic modules
• Telecommunication equipment power supplies

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 qualification status. Ensure the base part number matches the required voltage rating for the specific application. Confirm RoHS compliance requirements align with the manufacturing revision. Validate terminal solderability specifications against assembly process standards before procurement.

Selection Notes

Select this component when high-frequency operation requires fast reverse recovery characteristics. The avalanche rating provides robustness against inductive switching transients. Verify thermal resistance parameters match the intended heat dissipation environment. Ensure the DO-214AC footprint accommodates the design constraints.

Part Context

This device belongs to the BYG22 series of ultrafast SMD rectifiers manufactured by Vishay General Semiconductor. The series encompasses multiple voltage ratings including 50 V and 100 V variants. All models share identical mechanical dimensions and electrical characteristics except for the reverse voltage rating. The HE3 designation indicates halogen-free and RoHS-compliant construction.

Replacement Considerations

Compatible substitutes include BYG22D-E3/TR and BYG22D-M3/TR. These alternatives maintain the same 200 V rating and DO-214AC package but may differ in automotive qualification status.
