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。

供应A6059H开关电源PWM控制器电源IC
信息内容：特点： Current-Mode Type PWM Control Built-in Random Switching FunctionThe function reduces the EMI noise and enables a simplified (low-cost) EMI filter,by the slight- random-change of PMW frequency fOSC. Auto-Standby Function: The burst-oscillation enables the low standby power. Input Power PIN < 25mW at no load Built-in Startup Circuit, enabling low power consumption Brown-In / Brown-Out FunctionThe function enables the oscillation start/stop by externally rated input voltage and makes protections at low inputvoltage. Overcurrent Protection (OCP) with Built-in Input Compensation Circuit:The protection has less AC input voltage dependency. Overload Protection (OLP) with Built-in Delay Timer High Speed Latch Release FunctionThe function releases the latch immediately at AC supply OFF, after the latch protection operation. Bias-Assist Function, reducing Operating VCC voltage dropThe function improves the startup operation and makes a low VCC capacitor applicable. Lead...
