The single unidirectional channel is polarity-sensitive; for AC or bidirectional lines, two devices back-to-back or a dedicated bidirectional part is needed. ## Through-hole DO-201 — board-level fit Housed in a DO-201AA (DO-27) axial-lead package, the part mounts through-hole — the lead bend and hole pattern match the standard 0.100-inch pitch footprint common to legacy and new designs. Bulk packaging means the reel quantity is not fixed; MOQ is by the piece or tube.","metaTitle":"1.5KE27A B0G TVS Zener, 1500W, 23.1V Standoff, DO-201","metaDescription":"Active Taiwan Semiconductor 1.5KE27A B0G unidirectional TVS, 1500W peak pulse, 23.1V standoff, 37.5V clamp, -55°C to 175°C.
