The 11.4 V minimum breakdown voltage ensures the device starts clamping before the protected circuitry's absolute maximum rating is reached. ## Package and mounting — DO-201 axial The DO-201AA (DO-27) axial leaded package fits standard 0.100-inch pitch through-hole layouts; the cathode band identifies the unidirectional polarity. No power line protection feature is built in — this is a discrete transient suppressor, not a filtered TVS array.","metaTitle":"1.5KE12AHB0G TVS Diode, 1500W, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE12AHB0G Zener TVS, 1500W peak pulse, 10.2V standoff, 16.7V clamp, AEC-Q101 automotive grade.
