Procurement Notes
This component is designated as End of Life with the last available purchase date being May 31, 2011. Verify availability through authorized distributors or secondary markets. Confirm that the E3 suffix indicates compliance with RoHS Directive 2002/95/EC and WEEE 2002/96/EC standards before procurement.
Selection Notes
Select this part for designs requiring high voltage isolation up to 1500 V and fast switching characteristics. Ensure the TO-263AB package fits the PCB layout constraints. Validate thermal management capabilities against the specified junction-to-case thermal resistance. Consider the end-of-life status when planning long-term production runs.
Part Context
The BYS459B-1500SE3/45 belongs to the BYS459 series of high voltage damper diodes from Vishay General Semiconductor. This series includes variants such as the BYS459-1500S (TO-220AC) and BYS459F-1500S (ITO-220AC). All variants share similar electrical characteristics but differ in mechanical packaging and mounting configurations.
Replacement Considerations
No direct substitute part numbers are documented in the provided datasheet. Due to the End of Life status, alternative components must be evaluated based on matching electrical specifications and package compatibility.
