The package supports Tape & Reel or Cut Tape handling — the reel quantity is set by the reel diameter, not the part itself. No power line protection (the device is not rated for direct AC mains clamping) — the 1.5SMC550A is intended for DC rail or signal-line transient suppression where the working voltage stays below 495V.","metaTitle":"Littelfuse 1.5SMC550A TVS Diode, 1.5kW, 495V Standoff","metaDescription":"Littelfuse 1.5SMC550A Zener TVS diode, 1500W peak pulse power, 495V reverse standoff, 760V clamping.
