The reverse standoff voltage is 9.72V typical, with a breakdown voltage range starting at 10.8V minimum — sized to protect 12V automotive rails from load-dump and inductive transients. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE12HE3/54 as obsolete. No official successor is recorded. A board spin to a different package or pinout may be needed for a direct replacement. For a pin-compatible alternative within the same Circuit Protection family, a parametric search for 1.5kW axial 10.8V breakdown TVS with AEC-Q101 will surface current-production candidates from Vishay's P6KE or SA series — but no single order code is guaranteed to drop in without verifying the clamping profile and Ipp rating.","metaTitle":"1.5KE12HE3/54 Vishay TVS Zener, 1500W, AEC-Q101, Obsolete","metaDescription":"Vishay 1.5KE12HE3/54 Zener TVS, 1500W peak pulse, 17.3V clamp.
