Automotive TVS with AEC-Q101 trace
The SMAJ17CAQ-13-F: Its 17V reverse standoff voltage and 27.6V clamping maximum at 14.5A define the protection window for a 12V or 24V vehicle bus — the clamp triggers before downstream electronics see a destructive transient.
400W peak pulse at 10/1000 µs
The 14.5A peak pulse current at that waveform tells you the diode absorbs a single-shot surge of that magnitude without failing short.
DO-214AC (SMA) footprint and supply
Housed in the standard DO-214AC (SMA) surface-mount package, the SMAJ17CAQ-13-F shares the same PCB footprint as other SMA-packaged TVS diodes — a drop-in swap for an existing 17V bidirectional SMA layout. The part carries an Active product status, so it remains a current-design choice without end-of-life risk.
