Quad Array for ESD Protection
This quad monolithic silicon voltage suppressor is designed for applications requiring transient overvoltage protection capability. It is intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, medical equipment, and other applications. Its quad junction common anode design protects four separate lines using only one package. These devices are ideal for situations where board space is at a premium. Specification Features * SC88A Package Allows Four Separate Unidirectional Configurations * Low Leakage < 1 A @ 3 Volt * Breakdown Voltage: 6.1 Volt - 7.2 Volt @ 1 mA * Low Capacitance (90 pF typical) * ESD Protection Meeting IEC1000-4-2 Mechanical Characteristics * Void Free, Transfer-Molded, Thermosetting Plastic Case * Corrosion Resistant Finish, Easily Solderable * Package Designed for Optimal Automated Board Assembly * Small Package Size for High Density Applications 1
