Housed in the DO-214AC (SMA) surface-mount package, the SMAJ18CA-13 shares the same footprint as other SMA-series TVS diodes — a straightforward drop-in for existing layouts using this industry-standard body. Available in Tape & Reel (TR) or Cut Tape (CT) packaging, which which exact ordering code the buyer selects determines the reel quantity and handling method for pick-and-place.","metaTitle":"SMAJ18CA-13 Diodes Inc TVS Diode, 400W, 18V, SMA","metaDescription":"SMAJ18CA-13 bidirectional TVS diode, 400W peak pulse, 18V standoff, DO-214AC SMA.
