The 112A peak pulse current (8.65V min breakdown to 13.4V clamp) means it can absorb a direct lightning-induced surge on an automotive harness without failing short. Bidirectional — one device handles both positive and negative transients, saving a board position compared to back-to-back unidirectional diodes. The DO-201AA axial package is through-hole, easy to hand-solder or wave-solder, and the body marking is clear enough to read orientation in a rework station. Packaged in Tape & Box (TB), not reel — fine for through-hole assembly lines that feed axial parts from a tube or tray. No RoHS/REACH conflict noted; the TransZorb® series has been lead-free compatible for years.","metaTitle":"1.5KE9.1CAHE3_A/D Vishay TVS, 1500W, Bidirectional, DO-201AA","metaDescription":"Vishay 1.5KE9.1CAHE3_A/D bidirectional Zener TVS, 1500W peak pulse, AEC-Q101, 7.78V standoff, 13.4V clamp.
