The 58.1 V reverse standoff is the working voltage the protected node sees in normal operation; the TVS conducts only when a transient exceeds the 64.6 V minimum breakdown threshold. ## Voltage clamping chain and what the ratings mean In a protection circuit this means the downstream IC or bus sees no more than 92 V during a surge event — the gap between 58.1 V standoff and 92 V clamping is the TVS absorbing the transient energy. At 1.5 kW the clamping energy capacity is adequate for board-level protection on telecom line cards and power-supply input stages where the transient energy is bounded by upstream series impedance. ## Telecom deployment and temperature margin The listed application is telecom, which typically means equipment operating on 48 V or -48 V distribution rails — the 58.1 V standoff fits comfortably above 48 V nominal. Junction temperature rating is -55 °C to 150 °C, giving wide margin for outdoor cabinet or uncontrolled-ambient deployments. Power line protection is listed as \"No\", confirming this device protects a signal or secondary power rail rather than the AC mains entry point — do not specify it as the primary surge barrier on a power distribution board.","metaTitle":"1.5SMC68CA V7G TVS Diode, 1.5kW 92V Clamp","metaDescription":"1.5SMC68CA V7G unidirectional TVS diode, 1.5kW peak pulse, 92V max clamping, 58.1V standoff, DO-214AB SMC package.
