The SMAJ54CA-13-F: At a reverse standoff voltage of 54V, it clamps transients to 87.1V maximum — that is the voltage the downstream ICs see during a surge event. With a peak pulse current of 4.6A, this part handles moderate-energy transients on 48V or 54V rails — common in telecom, industrial, and automotive auxiliary supplies where the nominal bus sits at 48-54 VDC.
