Product details

Active automotive-grade TVS for 14V rails

The SMAJ14CAQ-13-F: It protects a single 14V nominal rail, clamping at 23.2V max during a 17.2A peak pulse (10/1000µs waveform) while dissipating 400W peak pulse power. The 400W rating means this part safely absorbs transient energy from load-dump or inductive kickback events in an automotive 12V system — the 14V reverse standoff sits above the nominal battery voltage, so it stays transparent during normal operation and only conducts when the line exceeds the breakdown threshold of 15.6V min.

Housed in a DO-214AC (SMA) surface-mount package, the SMAJ14CAQ-13-F mounts on standard PCB land patterns for this footprint.
