The "FemtoFarad" product family is specifically designed to protect sensitive electronic circuits from the threat of electrostatic discharge (ESD). "FemtoFarad" products react almost instantly to the transient voltage and effectively clamp it below 60 V, meaning less voltage stress during the clamp period and greater IC protection. The design of "FemtoFarad" products inherently produces a low capacitance part. In the off-state "FemtoFarad" is virtually invisible to the circuit. Installed from signal line to ground, the "FemtoFarad" device exhibits a high impedance and low capacitance that makes it transparent to high-speed digital circuits. Signals are not distorted or disrupted.
