Product Description

The CM1230 is a family of 2, 4 and 8 channel, very low capacitance ESD protection diode arrays in a CSP form factor. It is ideal for protecting systems with high data and clock rates or for circuits that need low capacitive loading. Each channel consists of a pair of ESD diodes that act as clamp diodes to steer ESD current pulses to either the positive or negative supply rail. A Zener diode is integrated between the positive and negative supply rails. The VCC rail is protected from ESD strikes and eliminates the need for a bypass capacitor to absorb positive ESD strikes to ground. Each channel can safely dissipate ESD strikes of ±8 kV, meeting the Level 4 requirement of the IEC61000?4?2 international standard as well as ±15 kV 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 ±15 kV.
