The 1.5KE10CAHA0G: The breakdown voltage is specified at a minimum of 9.5V, meaning the device begins conducting when the transient exceeds this threshold. The clamping voltage is capped at 14.5V at the peak pulse current, which defines the maximum voltage the protected circuitry sees during a surge — critical for selecting downstream components with sufficient voltage margin.
