TVS fuse board level protection

The CM1230 is a family of 2-, 4-, and 8-channel ultra-low capacitance ESD protection diode arrays in CSP form factors. It is suitable for protecting systems with higher data and clock rates, or circuits requiring low capacitive loads. Each channel includes a pair of ESD diodes that act as clamping diodes to divert ESD current pulses to the positive or negative supply rail. A Zener diode is integrated between the positive and negative supply rails. This protects the VCC rail from ESD spikes while eliminating the need for bypass capacitors to absorb positive ESD spikes to ground. Each channel can safely dissipate ESD spikes of ±8kV, meeting level 4 requirements of the IEC61000-4-2 international standard, and ±15kV air discharge requirements of the IEC61000-4-2 specification.
