0805ESDA Datasheet | Cooper Bussmann

Features : - The best ESD protection for high frequency, low voltage applications. - Exceeds testing requirements outlined in IEC 61000-4-2 - Extremely low capacitance - Very low leakage current - Fast response time - Bi-directional - Surface mount - Solder Termination What is it: The Voltage Variable Material (VVM) based on Surg X® polymer technology has unique property that it is highly preferred in ESD suppression application. The polymer matrix responds to an over-voltage condition by rapidly changing from a high impedance state to a low impedance state. Cooper Electronic Technologies How it Works: ESDA series are board level circuit protection devices designed exclusively for the fast, transient over-voltages associated with ESD. When a sufficient overvoltage occurs it exhibits a dramatic increase in the ability to conduct electrons. The nature of the material creates a bi-directional part, which means that only one device is required to provide plete ESD protection regardless of the surge polarity. In a typical application, the device is placed across a signal line leading to an integrated circuit and ground. The device exhibits minimal capacitance and is “invisible” to the ESDA Series Selection Guide: Part Number 0603ESDA 0805ESDA 41206ESDA Package Size 0603 0805 1206 Lines 1 1 4 Operating Voltage (VDC) 0 ~ 14 0 ~ 12 0 ~ 12 Capacitance (p F @ 1KHz ~ 1.8GHz) utilizes this polymeric matrix in the ESD suppression device family for fast response, ultra low capacitance, and very low current leakage. The device is activated by over-voltage threat and clamps to a low value to protect sensitive circuit ponents. circuit during the normal operation. Under normal operating voltages (typically 3 to 15V) the high impedance of the device insulates each signal line from ground. When an ESD event occurs, the Surg X® material switches to a conductive state within nanoseconds. The voltage across signal line collapses to the clamping level, and current is shunted through the...
