Housed in the DO-214AC (SMA) surface-mount package, it shares the standard footprint of the SMAJ family. The tape-and-reel supply supports automated pick-and-place for volume assembly. No power line protection means this TVS is intended for signal and low-power data lines, not for DC power buses or AC mains.","metaTitle":"SMAJ18CAQ-13-F Diodes Inc TVS Diode, 400W, 18V, AEC-Q101","metaDescription":"Active automotive TVS diode, 400W peak pulse, 18V reverse standoff, bidirectional, AEC-Q101 qualified, DO-214AC SMA package.
