This window means the protected circuit sees no more than 760 V across its terminals during a surge event, which is critical for downstream semiconductor withstand ratings. A single bidirectional channel handles both positive and negative transients on the same line, simplifying PCB layout for AC or bipolar DC buses. Surface-mount assembly with tape-and-reel packaging supports automated pick-and-place for volume production.","metaTitle":"Littelfuse 1.5SMC550CA TVS Diode, 1500W, DO-214AB","metaDescription":"Littelfuse 1.5SMC550CA bidirectional Zener TVS, 1500W peak pulse, 495V standoff, DO-214AB.
