Applications are listed as Automotive — suitable for clamping transients on CAN bus, LIN bus, sensor lines, and low-voltage data interfaces in vehicle electronics. ## DO-214AC SMA package — board-level integration note Housed in the DO-214AC (SMA) package with surface mount mounting, the SMAJ18AQ-13-F mates with standard SMA footprints — the cathode band on the package body orients the unidirectional channel. The supplier device package is SMA — the same mechanical outline as other SMA-packaged TVS diodes, so a board layout for a competitive SMA TVS accepts this part without a footprint change. Power line protection is marked No — this is a signal/data-line protector, not a primary power rail clamp; the 400W rating at 10/1000µs is typical for secondary protection on I/O lines.","metaTitle":"SMAJ18AQ-13-F Diodes Inc TVS, 400W, 18V, AEC-Q101, DO-214AC","metaDescription":"SMAJ18AQ-13-F Diodes Inc Zener TVS diode, 400W peak pulse, 18V reverse standoff, AEC-Q101 automotive grade, DO-214AC SMA package.
