No official successor is recorded. Sourcing runs through independent surplus and broker channels; availability and pricing are confirmed at RFQ against the BOM quantity. The clamping voltage at that peak current is 173 V max, meaning a 97.2 V standoff rail sees the line held below 173 V during the surge. Breakdown voltage starts at 108 V min, so the device begins conducting before the rail exceeds the standoff rating. Peak pulse current is 8.7 A under the same 10/1000 µs condition — the actual surge current the part can clamp at the rated power. ## Automotive AEC-Q101 qualification Part of the Automotive, AEC-Q101, TransZorb® series — qualified to the AEC-Q101 stress and reliability standard for discrete semiconductors used in automotive electronics. This includes temperature cycling, high-temperature reverse bias, and ESD screening. The DO-201AA axial package is through-hole, suited for high-reliability board-level mounting where the leaded form factor provides mechanical strain relief.","metaTitle":"1.5KE120HE3/73 Vishay TVS, 1500W, 97.2V Standoff, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE120HE3/73 TVS diode, 1500W peak pulse, 97.2V standoff, AEC-Q101.
