The CM1230-02CP 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 ±8kV, meeting the Level 4 requirement of the IEC61000-4-2 international standard as well as ±15kV air discharges per the IEC61000-4-2 specification.
Feature
- Two, four, and eight channels of ESD protection
- Low loading capacitance of 0.8pF typical
- Channel I/O to GND capacitance difference of 0.02pF typical is ideal for differential signals
- Minimal capacitance change with temperature and voltage
Applications
- I/O port protection including USB, 1394 and serial ATA
- LCD and camera data lines in wireless handsets that use high-speed serial interfaces.
- mobile handsets,notebook computers, DSCs, MP3 players,PDAs, etc.
