Power line protection is not supported, so do not use this as a mains surge suppressor; it is a signal- and low-power-rail TVS. The DO-201AA axial package is a through-hole footprint that mates with existing board layouts. Tape & Reel packaging supports axial-component auto-insertion for volume builds.","metaTitle":"1.5KE33CAHE3_A/C TVS Diode, 1500W, AEC-Q101, Vishay","metaDescription":"Vishay 1.5KE33CAHE3_A/C bidirectional TVS, 28.2V standoff, 45.7V clamp at 32.8A, 1500W peak pulse, AEC-Q101.
