When a surge hits, the device clamps at 328V maximum (:328V) while conducting 4.6A peak pulse current (:4.6A). The 1500W rating tells you the energy the part can absorb in a single pulse — enough for industrial power supplies, motor drive DC buses, or telecom rectifiers where the transient energy is moderate but repetitive. ## Bidirectional clamping for AC or polarity-agnostic lines That matters when the protected line carries AC or when field wiring polarity is not guaranteed — one part covers both directions without needing a series pair. The DO-214AB SMC footprint (:DO-214AB, SMC) is the standard large-body SMD package for 1.5kW TVS diodes; the cathode band is marked for orientation even though the bidirectional construction is polarity-insensitive. ## Active production — no last-time-buy pressure That means Littelfuse is still manufacturing it — no end-of-life notice, no last-time-buy deadline to track. The 1.5SMC series is a standard catalogue line with broad distribution coverage, so multi-source availability is the norm. Cut Tape (CT)), so it fits both high-volume reel-fed pick-and-place and prototype or repair bench orders. No special handling — standard MSL for SMC packages, store below 30°C in the original moisture barrier bag.","metaTitle":"1.5SMC220CA Littelfuse TVS Diode, 1500W Bidirectional","metaDescription":"1.5SMC220CA Littelfuse Zener TVS diode, 1500W peak pulse power, 185V standoff, 328V clamp.
