California Micro Devices' PAC VGA105, a new video graphics adapter (VGA) port protector, incorporates seven channels of electrostatic discharge (ESD) protection for signal lines commonly found in a VGA port for PCs. ESD protection is implemented with current steering diodes designed to safely handle the high peak surge currents associated with the IEC-1000-4-2 level 4 ESD requirements (8 kV contact discharge). ESD current pulses are diverted via the protection diodes into the positive supply rails or ground where they may be dissipated safely. The PACVGA105 is available in a 16-lead QSOP package.
