Use it on 256 V DC buses, telecom line cards, or industrial sensor power inputs where the energy in a lightning-induced surge or inductive kickback stays within the 1500 W envelope. ## DO-214AB SMC — footprint and temperature range Cut Tape works for prototype or low-volume builds where a full reel is excess. ## Active lifecycle — no end-of-life watch needed The active status means lead times follow standard semiconductor supply — no premium for end-of-life inventory.","metaTitle":"Littelfuse 1.5SMC300A TVS Diode, 1500W, 256V Standoff","metaDescription":"Littelfuse 1.5SMC300A Zener TVS diode, 1500W peak pulse power, 256V reverse standoff, 414V clamping at 3.7A.
