Housed in a DO-214AB (SMC) surface-mount package — the same footprint as the SMCJ series. The copper pad area under the cathode tab sets the thermal resistance; a solid ground-plane pour under the device improves peak-pulse energy handling. Supplied on Tape & Reel — standard for pick-and-place.","metaTitle":"Littelfuse 1.5SMC18C TVS Diode, 1500W, 15.3V Standoff","metaDescription":"Littelfuse 1.5SMC18C Zener TVS, 1500W peak pulse, 15.3V standoff, bidirectional, DO-214AB.
