BYG22DHE3_A/I

Overview

The BYG22DHE3_A/I 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 operates within a junction temperature range of -55 °C to +150 °C and supports a peak forward surge current of 35 A. Packaged in the SMA (DO-214AC) surface-mount format, it meets MSL level 1 standards and holds AEC-Q101 automotive qualification.

Feature Summary

• Avalanche-rated capability for energy dissipation during inductive load switching
• Soft recovery characteristic designed to minimize electromagnetic interference
• 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 automotive qualification status. Ensure the base quantity matches the required delivery mode, such as the 7-inch or 13-inch tape and reel specifications. Confirm RoHS compliance and material categorization requirements against project specifications before finalizing procurement orders.

Selection Notes

Select this component when circuit designs require controlled avalanche characteristics for handling inductive kickback. The 200 V rating suits applications operating below this threshold, while the 2.0 A average current capacity defines the continuous load limit. Consider the thermal resistance values relative to the expected ambient temperature and mounting pad layout to ensure safe junction temperature operation.

Part Context

This part belongs to the BYG22 series of ultrafast SMD rectifiers manufactured by Vishay General Semiconductor. The series encompasses variants with different reverse voltage ratings, including 50 V and 100 V options. The specific model utilizes the SMA (DO-214AC) case style, providing a standardized footprint compatible with common surface-mount assembly lines.

Replacement Considerations

Cross-reference with other Vishay BYG22D variants sharing the same electrical parameters and package type. Verify that any substitute maintains the required AEC-Q101 qualification and avalanche rating if those specific attributes are critical to the design.
