BY228TR

Overview

The BY228TR is a standard avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a glass passivated junction within a hermetically sealed SOD-64 package with plated axial leads. The device supports an average forward current of 3 A and withstands a reverse voltage of 1500 V. Key electrical parameters include a maximum forward voltage of 1.5 V at 5 A, a peak forward surge current of 50 A, and a total reverse recovery time of 20 μs. The component operates within a junction temperature range up to 140 °C.

Feature Summary

• Glass passivated junction for high reliability
• Hermetically sealed SOD-64 package
• Standard avalanche capability

Applications

• High voltage rectification
• Horizontal deflection circuits

Procurement Notes

Verify the specific ordering code against the required packaging format. The BY228TR designation corresponds to units supplied in a tape and reel configuration. Confirm that the SOD-64 package dimensions and lead specifications align with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring high reverse voltage blocking capabilities combined with moderate forward current handling. The SOD-64 through-hole package facilitates manual assembly or standard wave soldering processes. Ensure thermal management strategies account for the specified junction temperature limits during operation.

Part Context

This part belongs to the BY228 series of standard avalanche sinterglass diodes from Vishay. The 'TR' suffix specifically indicates the tape and reel packaging variant, distinguishing it from other bulk or ammopack configurations available within the same electrical specification family.

Replacement Considerations

Direct substitutes must match the 1500 V reverse voltage rating, 3 A average forward current, and SOD-64 package form factor. Verify equivalent reverse recovery times and forward voltage characteristics to ensure circuit compatibility.
