The device does not include power line protection circuitry — it is a standalone transient suppressor for signal or DC power rails.","metaTitle":"1.5SMC480A Littelfuse TVS Diode, 1.5kW, 408V Standoff","metaDescription":"Littelfuse 1.5SMC480A Zener TVS diode, 1500W peak pulse power, 408V reverse standoff, DO-214AB.
