Housed in the DO-201AA axial package (DO-27 equivalent), it mounts through-hole — the leaded body handles the mechanical stress of repeated surge events better than a surface-mount part in the same power class.","metaTitle":"1.5KE27CA B0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"1.5KE27CA B0G bidirectional TVS diode from Taiwan Semiconductor, 1500W peak pulse power, 23.1V standoff, 37.5V clamp.
