The 11.4 V minimum breakdown voltage and 16.7 V maximum clamping at 89.8 A (10/1000 µs pulse) define the protection window: the diode starts conducting before the downstream silicon sees damaging overvoltage, and the clamping voltage stays low enough to keep a 12 V-rated ECU or sensor module within its abs-max rating. ## Through-hole DO-201AA axial package — board-fit note The DO-201AA (DO-27) axial-lead package is a through-hole form factor that mates with 1.0 mm diameter holes on a standard 0.100-inch pitch. The lead bend radius and body length (9.1 mm typical) should be checked against the component height clearance on the board — the axial leads exit the body and bend down, so the seated height is roughly the body diameter plus the lead bend. Supplied in tape-and-reel packaging for automated insertion equipment. The reel quantity is set by the manufacturer's standard pack — confirm the reel count against the BOM volume before committing to a full reel buy.","metaTitle":"1.5KE12AHE3_A/C Vishay TVS Diode, 1500W, DO-201AA","metaDescription":"Vishay 1.5KE12AHE3_A/C automotive TVS, AEC-Q101, 1500W peak pulse, 10.2V standoff, DO-201AA axial.
