It clamps transients at 22.3V max when the surge current hits 67.3A, with a 12.2V reverse standoff voltage that lets it sit on a 12V rail without conducting during normal operation. The SQ-MELF C package is a surface-mount ceramic barrel — hand-solderable with care, but the metalized ends need a good reflow profile to avoid cold joints.
