The 72.7 V clamp ceiling means a 45 V rail sees its transient limited to roughly 1.6× the nominal, which is within the safe operating area of most downstream 60 V or 75 V-rated components.","metaTitle":"SMCJ45A-13 TVS Diode, 1.5kW, 45V Standoff, DO-214AB","metaDescription":"Diodes Inc SMCJ45A-13 Zener TVS, 1500W peak pulse, 45V reverse standoff, 72.7V clamp, DO-214AB SMC.
