The reverse standoff voltage is 7.78V, meaning the diode stays out of the circuit below that rail voltage and only starts conducting when the transient exceeds the minimum breakdown voltage of 8.65V. Power line protection is not supported — this is a unidirectional device intended for DC rail clamping, not AC mains.","metaTitle":"1.5KE9.1A R0G TVS Diode, 1500W, 7.78V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE9.1A R0G Zener TVS, 1500W peak pulse, 13.4V clamping, 117A Ipp. DO-201 axial, active production.
