Tower Crane Electric Spare Parts Diode

Diode, electronic components, a device with two electrodes, only allows the current flow from a single direction, many of the use of its rectifier is the application of the function. Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have the current direction we often call the "rectifying (Rectifying)" function. The most common function of diodes is to allow only current from a single direction (called forward bias), reverse the block (called reverse bias). Therefore, the diode can think of electronic version of the check valve.
Diode, also known as crystal diode, referred to as diode, in addition, there are early vacuum electronic diode; it is a one-way conduction current of electronic devices. Inside the semiconductor diode there is a PN junction of two lead terminals, this electronic device in accordance with the direction of the applied voltage, with unidirectional current transconductivity. In general, a crystal diode is a p-n junction interface formed by p-type semiconductor and n-type semiconductor sintering. In the interface on both sides of the formation of space charge layer, constitute a self-built electric field. When the applied voltage is equal to zero, the diffusion current is caused by the difference in the concentration of the carriers on both sides of the p-n junction and the drift current is equal to the drift current caused by the self-built electric field. This is also the diode characteristic under normal conditions.
