BYG22D-E3/TR

Overview

The BYG22D-E3/TR is an ultrafast avalanche rectifier from Vishay General Semiconductor, packaged in SMA (DO-214AC). It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 2.0 A. The device exhibits a peak forward surge current capability of 35 A and a maximum reverse recovery time of 25 ns. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V at 2.0 A and a reverse current of 1.0 μA at 25 °C. It operates within a junction temperature range of -55 to +150 °C and supports a non-repetitive pulse energy of 20 mJ in avalanche mode.

Procurement Notes

Verify the specific ordering code against official documentation to confirm package type and delivery mode. Confirm RoHS compliance status and material categorization requirements before procurement. Ensure the selected variant matches the required thermal resistance and operating temperature specifications for the target application environment.

Selection Notes

Select this component for designs requiring fast switching speeds and avalanche ruggedness. The 200 V rating suits intermediate voltage DC-DC conversion stages. Evaluate thermal management strategies based on the specified junction-to-ambient thermal resistance values under different mounting conditions. Verify compatibility with automated surface-mount assembly processes.

Part Context

This part belongs to the BYG22 series of ultrafast SMD rectifiers, which includes variants with different voltage ratings such as 50 V and 100 V. The series utilizes a glass-passivated junction technology designed for high-frequency operation. The E3 suffix indicates RoHS compliance and lead-free terminals, while the TR suffix specifies tape and reel packaging for automated manufacturing.

Replacement Considerations

Direct substitutes within the same family include BYG22A-E3/TR and BYG22B-E3/TR, differing primarily in their maximum repetitive peak reverse voltage ratings of 50 V and 100 V respectively. Cross-brand replacements must match the DO-214AC footprint, 2 A current rating, and 25 ns reverse recovery time specifications.
