The Tape & Box (TB) packaging suits hand-insertion or selective wave solder; the axial leads require no special footprint beyond standard 0.100-inch pitch holes. No power line protection rating flags this for signal and DC bus protection, not AC mains — keep it downstream of the fuse or breaker.","metaTitle":"1.5KE170CA A0G TVS Diode, 1500W, 234V Clamp, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE170CA A0G bidirectional TVS diode, 1500W peak pulse power, 162V breakdown, 234V clamp.
