The ESDA product family with SurgX® Technology is specifically designed to protect sensitive electronic circuits from the threat of electrostatic discharge (ESD). 4-line array can protect up to 4 isolated lines simultaneously with performance similar to individual chip devices. ESDA devices react almost instantaneously to the transient voltage and effectively clamp it in an average of 35V for the duration of the ESD transient, meaning less voltage stress during the clamp period and greater IC protection. The design of ESDA series inherently produces an ultra low capacitance part. In the off state the product is virtually invisible to the circuit. Installed from signal line to ground, it is especially transparent to the high-speed digital circuits due to the high off-state impedance and low capacitance. Signals are not distorted or disrupted as shown by extensive testing. With ESDA series, waveform definition stays true and high-speed signals do not suffer. ESDA series utilize a unique polymer-based material. The nature of the material creates a bi-directional part, which means that only one device is required to provide complete ESD protection regardless of the surge polarity. The combination of this material with proven thick film on ceramic technology produces a reliable, surface mount product that will help protect mobile communications, computers, data processing, test equipment, and many other electronic applications from ESD.
