Product details

Automotive-grade transient suppression for 24V rails

The SMCJ24CAQ-13-F: With a 24 V reverse standoff voltage, it clamps transients at 38.9 V max while handling 38.6 A peak pulse current.

What the clamping and breakdown specs mean for the BOM

The minimum breakdown voltage is 26.7 V, so a 24 V nominal rail that sags to 26 V during cranking still stays below the avalanche threshold. The 38.9 V clamping voltage at 38.6 A peak pulse current sets the maximum voltage the downstream circuitry sees during a surge event — the protected IC's abs-max rating must exceed this clamp level.
