Single unidirectional channel — cathode band marks the polarity; reverse insertion defeats the clamping function, so the silkscreen orientation must match the protected rail.","metaTitle":"1.5KE20AHB0G TVS Diode, 1500W, 17.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE20AHB0G automotive TVS, 1500W peak pulse, 17.1V standoff, AEC-Q101 qualified.
