UCLAMP0504A.TCT

The uClamp0504A of TVS arrays are designed to protect sensitive electronics from damage or latch-up due to ESD. They are designed for use in applications where board space is at a premium. Each device requires less than 2.9mm² of PCB area and will protect up to four lines. They are unidirectional devices and may be used on lines where the signal polarities are above ground.TVS diodes are solid-state devices designed specifically for transient suppression. They feature large cross-sectional area junctions for conducting high transient currents. They offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation.The uClamp0504A may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small SC-89 package makes them ideal for use in portable electronics such as cell phones, PDA's, notebook computers, and digital cameras. These devices feature a lead-free, matte tin lead finish. They are compatible with both lead free and SnPb assembly techniques.
