Product details

The SMAJ7.0CA-13: When the protected rail sees a transient, the device clamps at 12V maximum at the rated 33.3A peak pulse current, holding the downstream circuitry below its absolute maximum rating.

Breakdown and standoff — the trigger thresholds

Reverse standoff voltage is 7V, meaning the TVS draws negligible leakage below that rail voltage. Breakdown starts at 7.78V minimum, so a 7V supply riding at 5% tolerance (7.35V) stays below the avalanche threshold with margin.

Package and board integration

The two-pad layout is shared across the SMAJ family, so a single PCB land pattern serves the full voltage range from 5V to 188V standoff.

Frequently asked questions

What package does SMAJ7.0CA-13 come in?

DO-214AC (SMA) surface mount package, supplied on Tape & Reel (TR) or Cut Tape (CT). The SMA footprint is shared across the SMAJ family for voltage-range flexibility on one PCB layout.
