The SMC footprint is larger than the SMA/SMB siblings, providing better thermal dissipation for the 1500 W pulse rating — a consideration for the PCB copper area under the cathode tab.","metaTitle":"1.5SMC43A Littelfuse TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC43A Zener TVS diode, 1500W peak pulse, 36.8V standoff, DO-214AB.
