The 1.5 kW rating is a peak-pulse figure — continuous dissipation is far lower and is set by the board-level thermal design, not by this surge rating.,.","metaTitle":"Littelfuse 1.5SMC68A TVS Diode, 58.1V Standoff","metaDescription":"Littelfuse 1.5SMC68A unidirectional TVS diode, 58.1V standoff, 92V clamping, 1.5kW peak pulse, DO-214AB SMC surface mount.
