- DVI interfaces
- Cordless telephones
- Wireless data (WAN/LAN) systems
- PDAs
DESCRIPTION
The IP4220CZ6 is designed to protect I/Os being sensitive concerning capacitive load, such as USB 2.0, Ethernet, DVI etc. from destruction by Electro Static Discharges (ESD). Therefore, the IP4220CZ6 incorporates four pairs of ultra-low capacity rail-to-rail diodes plus an additional Zener diode to provide protection to downstream signal and supply components from Electrostatic Discharge (ESD) voltages as high as ±8 kV contact discharge. Due to the rail-to-rail diodes being connected to the Zener diode, the protection is working independent form the availability of a supply voltage. The IP4220CZ6 is fabricated using thin film-on- silicon technology and integrates 4 ultra-low capacity rail-to-rail ESD protection diodes in a miniature 6-lead SOT457 package.
