The 70.1 V reverse standoff (typ) is the working voltage your rail should sit below; when a surge fires, the clamping ceiling at 13.3 A peak pulse clamps at 113 V max. The 77.9 V minimum breakdown and 113 V clamping define the protection window — a 70 V rail sees roughly 40 V of headroom before breakdown engages, and the clamping ratio keeps the transient energy off the downstream load. At 13.3 A through the clamping event the part is absorbing 1.5 kW for the 1 ms pulse window, which is the exact stress the 1500 W rating is sized for. ## Temperature, polarity, and mounting Single bidirectional channel — there is no polarity orientation to mis-set on the board, which simplifies layout on a symmetric rail pair or a floating DC bus. Surface-mount SMC body lands on the board with a reflow or wave profile; the large cathode tab gives a solid thermal path to the pad, and the body sits high enough above the board to avoid conformal-coat interference on most mid-density layouts. ## Active status and sourcing posture The PBFREE suffix confirms lead-free termination plating, which matters for RoHS compliance in any product shipping to markets with REACH/RoHS requirements.","metaTitle":"1.5SMC82CA BK PBFREE TVS Diode, 1500W, 113V Clamping","metaDescription":"Central Semiconductor Corp bidirectional Zener TVS diode, 1500W peak pulse, 113V clamping, DO-214AB SMC.
