Breakdown occurs at 485V minimum, and the clamping voltage is held to 698V maximum at the 2.1A peak pulse current. This 213V window between standoff and clamp means the diode absorbs transients without clipping the nominal rail, but the clamp voltage is high enough that downstream components must be rated for at least 700V peak. Power line protection is marked 'No', so this part is intended for DC power or signal lines, not AC mains. ## Package, mounting, and temperature grade The standard SMC footprint with a 0.050-inch lead pitch is shared across the 1.5SMC series, so a single PCB land pattern serves the whole power range. Cut Tape works for prototype or low-volume rework. Sourced to order against BOM quantities. No stock-holding claim — each RFQ is validated against live distributor inventory.","metaTitle":"Littelfuse 1.5SMC510CA TVS Diode, 1500W, 434V Standoff","metaDescription":"Littelfuse 1.5SMC510CA bidirectional TVS diode, 1500W peak pulse, 434V reverse standoff, 698V clamp.
