Clamping specs and fit for 8.5 V rails
The SMAJ8.5CA-13: Reverse standoff voltage is 8.5 V typical; breakdown occurs at 9.44 V minimum, clamping at 14.4 V maximum with a peak pulse current of 27.7 A. The single bidirectional channel protects signal or power lines that swing both sides of ground — common on RS-485, CAN, or audio interfaces where a unidirectional part would clip one polarity.
