With a minimum breakdown of 12.4 V and a clamping ceiling of 18.2 V at 82.4 A peak pulse current, the diode sits above a 12 V nominal rail, staying inactive during normal operation and clamping inductive kickback or load-dump transients before they reach downstream semiconductor nodes. ## AEC-Q101 and the 175°C junction ceiling The -55°C to 175°C junction temperature range gives headroom over the worst-case engine-bay ambient; derating curves in the datasheet govern how much of the 1500 W peak the part can absorb at elevated case temperature. ## Active production — no successor on record Axial DO-201AA package — the through-hole footprint has been a standard TVS form factor for decades, so board-level replacement on legacy automotive control modules is straightforward compared to switching to a surface-mount alternative.","metaTitle":"Vishay 1N6274AHE3_A/C TVS Diode, 1500W Peak Pulse, AEC-Q101","metaDescription":"Vishay 1N6274AHE3_A/C automotive Zener TVS, 1500W peak pulse, 12.4V breakdown, 18.2V clamping.
