The 1.5SMC220: That power rating defines the energy it can clamp in a single surge event — a 4.6 A peak pulse current at the 344.4 V clamping voltage.
Littelfuse lists the 1.5SMC220 as obsolete. No pin-compatible replacement from Littelfuse is documented; a functional replacement would require verifying the clamping voltage and package footprint against the BOM position.
