Description:
  The UESD54B 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, each device will protect up to four 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 UESD54B 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抯, notebook computers, and digital cameras

UESD54B适用于保护四路单向数据线的静电保护，其SC70-5的小型封装是各种便携式设备电路板的设计的选择，目前对于ON.ST PHILLIPS,VISHAY等品牌的同类产品，具有的性价比。
