The junction temperature range spans -55°C to +175°C, covering under-hood and engine-bay ambient where the TVS absorbs repetitive load-dump transients. The DO-201AA axial package is through-hole, so the thermal path runs through the lead wires into the PCB pads — the 1500 W rating assumes a 25°C ambient and proper copper land area to sink the pulse heat. ## Sourcing reality for a discontinued TVS The closest functional replacement would be a current-production 1.5KE series part with the same standoff voltage and package — but the AEC-Q101 automotive grade narrows the field.","metaTitle":"1.5KE180HE3/54 TVS Diode, 1500W, 146V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE180HE3/54 Zener TVS, 1500W peak pulse, 146V standoff, AEC-Q101.
