Bidirectional 18V rail clamp in a 1.5 kW package
It is a single bidirectional device, meaning one component protects against both positive and negative overvoltage events on the same line — useful on AC-coupled or bipolar signal paths where polarity is not fixed. At the clamping voltage of 32.2 V max, the peak current reaches 46.6 A — enough for many industrial and automotive transient scenarios without cascading to a larger package.
Breakdown and clamping margins for BOM fit
Minimum breakdown voltage is 20 V, which sits 2 V above the 18 V reverse standoff. This gap gives headroom for normal rail ripple and tolerance without nuisance clamping. The maximum clamping voltage of 32.2 V sets the upper bound the downstream circuitry must survive — factor that into the derating of any DC-DC converter input or linear regulator fed from this rail. No power line protection feature is claimed — this is a signal or low-power rail protector, not a mains-side suppressor.
