Rated for 400 W peak pulse power, this part handles the kind of short-duration surges you see from inductive kickback or ESD events on a 12 V automotive or industrial bus. The single-channel unidirectional construction means it only protects one polarity — for AC or bidirectional lines you would need two devices or a bidirectional variant. ## DO-214AC SMA — board-fit and sourcing Housed in the standard DO-214AC (SMA) surface-mount package, the SMAJ14A-13 uses a footprint shared by countless TVS diodes and Schottky rectifiers. The mounting is surface-mount, and the part is available in both Tape & Reel and Cut Tape options — the reel suits automated pick-and-place for production, while cut tape works for prototype or repair bench runs. ## Active production — no lifecycle worry Because it is a mainstream TVS in a common package, second-source equivalents exist from other manufacturers (e.g., Littelfuse, Vishay, ST) with the same DO-214AC footprint and similar electrical specs. If you need a pin-compatible alternative for a second-source hedge, the SMAJ14A-13's base product number is SMAJ14, and any unidirectional 14 V TVS in SMA package with a 400 W rating will drop in.","metaTitle":"SMAJ14A-13 Diodes Inc TVS, 14V Standoff, 23.2V Clamp","metaDescription":"SMAJ14A-13 unidirectional TVS diode, 14V reverse standoff, 23.2V clamp at 17.2A, 400W peak pulse.
