BYG24D-E3/TR3

Overview

The BYG24D-E3/TR3 is a fast avalanche surface-mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and operates in the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward current of 1.5 A at 65 °C. Key electrical parameters include a maximum instantaneous forward voltage of 1.25 V at 1.5 A, a maximum reverse current of 1 µA at 25 °C, and a maximum reverse recovery time of 140 ns. It withstands a peak forward surge current of 30 A and handles 20 mJ pulse energy in avalanche mode.

Procurement Notes

Verify that the ordering suffix matches the required packaging quantity and reel diameter. Confirm RoHS compliance status and check for specific automotive qualification requirements if applicable to the target application environment. Ensure the component meets the necessary thermal resistance ratings for the intended operating conditions.

Selection Notes

Select this component when a fast recovery rectifier with avalanche capability is required in a compact surface-mount form factor. Consider the 200 V reverse voltage rating and 1.5 A current capacity against circuit demands. Evaluate the thermal management needs based on the specified junction-to-case and junction-to-ambient thermal resistances.

Part Context

This part belongs to the BYG24 series, which includes variants with different reverse voltage ratings such as 400 V and 600 V. All members share the same physical package and general performance characteristics, differing primarily in their breakdown voltage specifications. The series is designed for efficient high-frequency operation in modern power conversion topologies.

Replacement Considerations

Direct substitutes within the same family include BYG24G-E3/TR3 and BYG24J-E3/TR3. These parts offer higher reverse voltage ratings of 400 V and 600 V respectively while maintaining identical current handling and package dimensions.
