Key Specifications

The UESD6V8Lxx of TVS diode array is designed to protect sensitive electronics from damage or latch-up due to ESD, for use in applications where board space is at a premium. It is unidirectional device and may be used on lines where the signal polarities are above ground. UESD6V8L4A and UESD6V8L4B protect up to four lines while UESD6V8L5A6 and UESD6V8L5B will protect up to five lines. TVS diodes are solid-state devices feature large cross-sectional area junctions for conducting high transient currents, specifically for transient suppression. It offers desirable characteristics for board level protection including fast response time, low operating, low clamping voltage, and no device degradation. The UESD6V8Lxx may be used to meet the immunity requirements of IEC 61000-4-2, level 4. The small package makes them ideal for use in portable electronics such as cell phones, PDA’s, notebook computers, and digital cameras. The UESD6V8Lxx is fabricated using dual diffusion technology, offer low junction capacitance (20pF), which is required in high speed signal protection application.
