BYS459B-1500SE3/81

Overview

The BYS459B-1500SE3/81 is a high voltage damper diode manufactured by Vishay General Semiconductor - Diodes Division. It features a TO-263AB (D²Pak) surface-mount package with an exposed heatsink tab for thermal management. The device provides a maximum repetitive peak reverse voltage of 1500 V and supports a maximum average forward rectified current of 10 A. Key electrical characteristics include a fast reverse recovery time of 220 ns, a typical junction-to-case thermal resistance of 2.0 °C/W, and a peak forward surge current rating of 130 A.

Feature Summary

Glass passivated chip junction
Fast reverse recovery time
Low switching loss and high efficiency
High forward surge capability

Applications

High voltage and high frequency rectification of switching mode inverters
Converters
Freewheeling applications
CRT horizontal deflection circuits

Procurement Notes

This component is designated as End of Life with a final purchase date of May 31, 2011. Verify the specific ordering suffix 'E3/81' to confirm compliance with RoHS Directive 2002/95/EC and WEEE 2002/96/EC standards. Ensure that the tape and reel delivery mode matches the required manufacturing specifications for the TO-263AB package.

Selection Notes

Select this part for designs requiring high blocking voltage and rapid switching performance in power conversion topologies. Consider the 2.0 °C/W thermal resistance when designing the PCB copper area or heatsinking interface. Validate that the operating junction temperature range of -55 °C to +150 °C aligns with the environmental conditions of the target application.

Part Context

The BYS459B-1500SE3/81 belongs to the BYS459 series of high voltage damper diodes from Vishay. This family includes variants such as the BYS459-1500S and BYS459F-1500S, which share similar electrical ratings but differ in package types like TO-220AC and ITO-220AC. The E3 suffix indicates consumer grade compliance, while the /81 suffix specifies the tape and reel packaging format.
