Obsolete — sourcing through independent distribution
The 1.5KE8.2CHE3/73: The DO-201AA axial package and 1500W peak pulse rating are the critical parameters to match in any replacement evaluation.
Automotive-grade transient protection — AEC-Q101 qualified
This TransZorb® Zener TVS is from the Automotive series and carries AEC-Q101 qualification. That means it is qualified for automotive-grade stress and reliability screens — temperature cycling, high-temperature reverse bias, and ESD/latch-up per the AEC-Q101 discrete semiconductor qualification standard. The part provides a single bidirectional channel — it clamps both polarities of a transient, which is the typical configuration for protecting AC-coupled or floating signal lines. The reverse standoff voltage is 6.63V, meaning the TVS draws negligible leakage below that rail voltage.
Package and replacement fit — DO-201AA axial
The 1.5KE8.2CHE3/73 is housed in a DO-201AA (DO-27) axial-lead package with through-hole mounting. The supplier device package is designated 1.5KE. Any replacement candidate must match this footprint — the body diameter and lead spacing of the DO-201AA — and the 1500W peak pulse rating at the same 10/1000µs test condition. The part ships in Tape & Box (TB) packaging, which is the standard bulk format for axial diodes.
