BYV28-200-TR

Overview

The BYV28-200-TR is an ultra-fast avalanche sinterglass diode from Vishay, rated for a repetitive peak reverse voltage of 200 V and an average forward current of 3.5 A. It features a maximum forward voltage of 1.1 V at 5 A and a peak reverse recovery time of 30 ns. The device operates within a junction temperature range of -55 °C to +175 °C and supports a peak non-repetitive forward surge current of 90 A.

Feature Summary

• Controlled avalanche characteristic for inductive load switching
• Ultra-fast recovery time with low forward voltage drop
• Hermetically sealed glass passivated junction

Applications

• Very fast rectification in switch mode power supplies

Procurement Notes

Verify the specific ordering code matches the required packaging format. Confirm that the component meets all necessary automotive qualification standards if intended for such environments. Ensure thermal management aligns with the specified maximum thermal resistance values under actual mounting conditions.

Selection Notes

Select this component when high-speed rectification and avalanche ruggedness are required in a through-hole axial package. Consider the 3.5 A continuous current rating and 200 V blocking capability against circuit demands. Evaluate thermal constraints based on the lead length and ambient temperature operating limits.

Part Context

This part belongs to the BYV28 series of ultra-fast avalanche sinterglass diodes manufactured by Vishay Semiconductors. The series includes variants with different reverse voltage ratings while maintaining identical current handling and package specifications.
