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.","metaTitle":"Littelfuse 1.5SMC220 TVS Diode, 1500W, 185V Standoff","metaDescription":"Obsolete Littelfuse 1.5SMC220 Zener TVS diode, 1500W peak pulse, 185V standoff, DO-214AB.
