Description

Diode  Features And Applications

Diode classification:Schottky diodes,rectifier diode,Zener diode,Bidirectional trigger diode,Solar blocking diode,Silicon carbide Schottky diode,Helium diode,Power diode,Discrete diode.
Among diodes and electronic components, a device with two electrodes allows current to flow only in a single direction, and many of them use the function of rectification. The varactor is used as an electronically tunable capacitor. The current directionality of most diodes is often referred to as the “rectifier” function. The most common function of a diode is to allow only current to pass in a single direction (called forward bias) and reverse in reverse (called reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
The crystal diode is a pn junction formed of a p-type semiconductor and an n-type semiconductor, and a space charge layer is formed on both sides of the interface, and a self-built electric field is built. When there is no applied voltage, the diffusion current caused by the difference in carrier concentration on both sides of the pn junction is equal to the drift current caused by the self-built electric field, and is in an electric equilibrium state. When the outside is biased by the forward voltage, the mutual suppression of the external electric field and the self-built electric field causes the diffusion current of the carrier to increase to cause a forward current. When the outside has a reverse voltage bias, the external electric field and the self-built electric field are further strengthened to form a reverse saturation current I0 that is independent of the reverse bias voltage value within a certain reverse voltage range. When the applied reverse voltage is high to a certain extent, the electric field strength in the space charge layer of the pn junction reaches a critical value to generate a multiplication process of carriers, which generates a large number of electron hole pairs, and generates a large reverse breakdown current. It is called the breakdown phenomenon of the diode. The reverse breakdown of the pn junction is characterized by Zener breakdown and avalanche breakdown.
