The SMC footprint is larger than the smaller SMA/SMB siblings, offering better thermal dissipation for the 1500W pulse rating — the copper pad area under the cathode tab directly sets the junction-to-ambient thermal resistance during a surge. If a different clamping voltage is needed later, the BOM can be adjusted without a PCB layout change.","metaTitle":"Littelfuse 1.5SMC33A TVS Diode, 1500W, 28.2V Standoff","metaDescription":"Littelfuse 1.5SMC33A Zener TVS diode, 1500W peak pulse power, 28.2V reverse standoff, 45.7V clamping.
