BYG22D-M3/TR

Overview

The BYG22D-M3/TR is an ultrafast avalanche SMD rectifier manufactured by Vishay General Semiconductor - Diodes Division. 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. 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 rated for operating junction and storage temperatures ranging from -55 °C to +150 °C.

Procurement Notes

Verify that the ordering suffix /TR corresponds to the 7-inch diameter plastic tape and reel delivery mode as specified in the datasheet. Confirm compliance requirements such as halogen-free status and RoHS directives associated with the M3 designation. Ensure the component meets the specific environmental standards required for the target application environment.

Selection Notes

Select this component when high-frequency rectification or freewheeling functionality is required in compact surface-mount designs. The 200 V reverse voltage rating and 2.0 A average current capacity define its operational limits. Consider the thermal resistance values relative to the intended PCB layout and ambient temperature conditions to ensure reliable operation within the specified junction temperature range.

Part Context

This part belongs to the BYG22 series of ultrafast avalanche SMD rectifiers, which includes variants with different reverse voltage ratings such as 50 V and 100 V. All members of the series share identical physical dimensions, package type, and general electrical characteristics except for the maximum repetitive peak reverse voltage parameter. The series is designed for use in various consumer, computer, automotive, and telecommunication applications requiring fast switching capabilities.

Replacement Considerations

Direct substitutes within the same series include BYG22A-M3/TR and BYG22B-M3/TR, differing only in their maximum repetitive peak reverse voltage ratings of 50 V and 100 V respectively. Verify that the alternative part's voltage rating meets or exceeds the circuit requirements before substitution.
