Product details

TVS clamp ratings for the rail

The 1.5SMBJ14A: It clamps transients at 23.2 V maximum when the peak pulse current reaches 64.7 A. The reverse standoff voltage is 14 V, with a minimum breakdown of 15.6 V. This means the diode stays transparent below 14 V and starts conducting only when the line exceeds that threshold, protecting a 12 V or 14 V rail from overvoltage events.

Package and board-fit

Power line protection is not specified — this is a signal- or low-voltage rail TVS, not a mains transient suppressor.
