Diodes are used to let electricity flow in a single direction through a circuit.Zener diodesdiffer from other types of diodes in that, when you connect them in the reverse direction in a circuit, such that current flows the other way across a diode, they let a small leakage current flow. ...
The meaning of ZENER DIODE is a silicon semiconductor device used especially as a voltage regulator.
1、VCC Pin(供电PIN) 当启动电源时,透过外部启动电阻提供起动电流对Vcc电容充电,Vcc电压达到UVLO on 18V时,IC开始工作,此时电压暂时由VCC电容提供,一直等到输出的LED灯串电压建立后再透过Zener diode 和super fast diode将输出LED灯串电压提供给IC使用。如果VCC电压低于UVLO off欠压停止工作点8V时会关闭输出电路减少...
The European Union‘s Ecodesign Directive 2009/125/EC sets mandatory ecological requirements for products running most of their usage time in stand-by mode. Diotec‘s LDO, Schottky Diode, Zener Diode and Superfast Efficient Rectifier all according to it.
A protection diode is a type of Zener diode. Zener diodes can be used not only as protection diodes but also as constant-voltage regulators. Protection diodes are specifically designed to protect electronic circuits from ESD and other transient pulses. In contrast, Zener diodes for constant-...
