Product details

Clamping voltage and breakdown margin

The SMCJ11AQ-13-F: Breakdown occurs at a minimum of 12.2V, giving a 1.2V margin above the 11V standoff — the TVS stays transparent during normal operation and only conducts when the transient exceeds the breakdown threshold. The 18.2V clamping voltage at 82.4A peak pulse current defines the maximum voltage the downstream circuitry sees during a surge event — a 12V automotive rail clamped to 18.2V keeps the bus within the safe operating area of most 12V-rated ICs.

Frequently asked questions

Is SMCJ11AQ-13-F automotive qualified?

Yes, it carries AEC-Q101 qualification, making it suitable for automotive-grade applications such as ECU power supply clamping, sensor line protection, and battery-line transient suppression.
