The CM1230 is a family of 2, 4 and 8 channel, very low capacitance ESD protection diode arrays in CSP form factor. This device is ideal for protecting systems with high data and clock rates or for circuits that require low capacitive loading. Each channel consists of a pair of ESD diodes that act as clamp diodes that steer positive or negative ESD current pulses to either the positive or negative supply rail. A zener diode is integrated into the array between the positive and negative supply rails. The VCC rail is thus protected from ESD strikes and eliminates the need for a bypass capacitor to absorb positive ESD strikes to ground. Each channel of the CM1230 can safely dissipate ESD strikes of 8kV, meeting the Level 4 requirement of the IEC61000-4-2 international standard for contact discharges as well as 15kV air discharges per the IEC61000-4-2 specification. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than 15kV.
