For a 24 VDC input rail, the clamping ceiling of 20.1 V sits below the withstand voltage of most downstream ICs, so the part protects downstream components from inductive kickback and ESD events on that rail. The 74.6 A peak pulse current at the clamping voltage confirms the diode's surge-handling capability matches well against input lines that might see significant transient energy. ## Active production status and sourcing posture Diotec Semiconductor lists the 1.5SMCJ11 as Active.","metaTitle":"Diotec 1.5SMCJ11 TVS Diode, 1.5 kW Peak, 20.1V Clamping","metaDescription":"Diotec 1.5SMCJ11 unidirectional Zener TVS diode, 1500 W peak pulse, 11 V standoff, 20.1 V clamping, DO-214AB SMC.
