The 73.8 V minimum breakdown voltage means it starts conducting before the rail hits 80 V, leaving margin for a 72 V absolute-maximum downstream regulator. The full operating junction temperature range is -55 °C to 175 °C, covering cold-crank and hot-soak conditions. The TransZorb construction uses a glass-passivated junction in a DO-201AA (DO-27) axial-lead package. Through-hole mounting keeps the thermal path to the board short, which matters when the 1.5 kW pulse dumps heat into the lead frame. ## Sourcing an obsolete part — what to expect For a BOM line that requires this exact AEC-Q101 TVS, the procurement path is through independent distribution. We source and quote to order against an RFQ — each lot is verified for authenticity and date code before it ships.","metaTitle":"1.5KE82HE3/54 Vishay TVS, 1.5kW, 66.4V Standoff, DO-201","metaDescription":"Vishay 1.5KE82HE3/54 Zener TVS, 1500W peak pulse, 66.4V reverse standoff, AEC-Q101 qualified.
