Its 14V reverse standoff voltage means it stays off below 14V, so it won't leak on a healthy 12V bus. The minimum breakdown voltage is 15.6V, giving a guard band before the diode starts conducting.
The suffix in the order code indicates a lead-free, RoHS-compliant finish — no change in electrical performance versus the standard SMAJ14CA, but required for newer environmental compliance directives.
It is a single-channel bidirectional device, clamping both positive and negative transients symmetrically.
The suffix indicates a lead-free, RoHS-compliant termination finish. It does not affect electrical specifications compared to the standard SMAJ14CA.
