Breakdown starts at 71.3 V minimum, and the clamp hits 104 V at 14.6 A. That 39 V window between standoff and clamp is the headroom the downstream circuitry must survive. The 1500 W rating is the peak pulse power into a 10/1000 µs surge — a standard automotive load-dump or inductive kickback pulse. ## Package and board integration — DO-201AA axial leaded The DO-201AA (DO-27) axial package is through-hole — the leads are 0.96 mm diameter tin-plated copper, and the body is 5.3 mm diameter by 7.5 mm long. It mounts into a 1.1 mm hole on a standard PCB or terminal block; the axial form factor suits point-to-point wiring in power distribution boxes as well as PCB layouts. No power line protection (the diode is unidirectional, not a steering array), so it clamps one polarity only. For AC or bidirectional rails, two devices back-to-back are needed. ## Sourcing and lifecycle — active, no obsolescence concern The base product number is 1.5KE75; the full suffix (AHE3_A/D) encodes the AEC-Q101 automotive grade and the tape-and-box packaging.","metaTitle":"1.5KE75AHE3_A/D Vishay TVS, 1500W, 64.1V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE75AHE3_A/D Zener TVS diode, 1500W peak pulse, 64.1V standoff, AEC-Q101 automotive, DO-201AA axial.
