BYV27-150-TR

Overview

The BYV27-150-TR is an ultra-fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a controlled avalanche characteristic and a glass passivated junction within a hermetically sealed SOD-57 package. The device supports a repetitive peak reverse voltage of 150 V and an average forward current of 2 A, with a peak forward surge current capability of 50 A. Electrical specifications include a maximum forward voltage of 1.07 V at 3 A and a maximum reverse recovery time of 25 ns. The component operates across a junction and storage temperature range from -55 °C to +175 °C.

Feature Summary

• Controlled avalanche characteristic for inductive load switching
• Ultra-fast recovery time with low forward voltage drop
• Glass passivated junction in a hermetically sealed package

Applications

• Very fast rectification diodes for switch mode power supplies
• High frequency rectification applications
• Switch mode converters and inverters

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm packaging format. The datasheet indicates that the TR suffix corresponds to tape and reel packaging, while other suffixes may denote ammopack configurations. Confirm minimum order quantities and unit counts per reel directly from the manufacturer's ordering information section before procurement.

Selection Notes

Select this component when high-speed switching and avalanche ruggedness are required. The 150 V rating suits circuits operating below this threshold. Ensure thermal management accounts for the specified thermal resistance values based on lead length or PCB spacing. Validate performance under maximum junction temperatures up to 175 °C for reliability in demanding environments.

Part Context

This part belongs to the BYV27 series of ultra-fast plastic rectifiers designed for high-frequency applications. The series includes variants with different reverse voltage ratings, such as 50 V, 100 V, and 200 V, all sharing similar electrical characteristics and package types. These devices are engineered for efficiency and low switching losses in consumer, computer, and telecommunications equipment.

Replacement Considerations

Compatible substitutes within the same family include BYV27-50, BYV27-100, and BYV27-200. When replacing, ensure the alternative part meets or exceeds the 150 V reverse voltage requirement and maintains comparable forward current and recovery time specifications.
