1500W surge clamp for 18.8V rails
The 1.5SMC22A_R1_00001: The 1500W rating means it absorbs that energy without failing — useful for protecting downstream ICs on power input or signal lines in industrial control and telecom gear.
Package and thermal envelope
The SMC footprint is larger than the SMA/SMB siblings, which helps with PCB heat sinking — the copper pad area under the package directly influences the thermal impedance for sustained pulse trains. Tape & Reel packaging (Cut Tape also available) suits automated pick-and-place assembly.
