AEC-Q101 TransZorb for 154 V rails
The 1.5KE180AL-83E3/72 is a unidirectional TransZorb® TVS diode from Vishay's Automotive series, AEC-Q101 qualified.
Lifecycle reality — obsolete, sourced on request
For a BOM that already specifies this exact order code, the only procurement path is the secondary market. The AEC-Q101 qualification and the TransZorb series name are still relevant for verifying the part's pedigree when sourcing from surplus inventory.
Temperature range and package fit
The DO-201AA axial package requires a through-hole mounting process—verify the lead spacing and hole diameter match the existing PCB layout before committing the BOM line.
