Chip diode what is?

It is an electronic device with unidirectional conduction current. There is a PN junction two lead terminals inside the semiconductor diode. This electronic device has unidirectional current transduction according to the direction of the applied voltage. In general, a chip crystal diode is a p-n junction interface formed by sintering a p-type semiconductor and an n-type semiconductor. A space charge layer is formed on both sides of the interface to form a self-built electric field. When the applied voltage is equal to zero, the diffusion current caused by the concentration difference of carriers on both sides of the p-n junction is equal to the drift current caused by the self-built electric field, which is also the diode characteristic under normal conditions.

What is the role of the patch triode

Measure the interelectrode resistance. Place the multimeter in R× 100 or R× 1K block, and test according to six different connection methods of red and black pens. Among them, the positive resistance value of the emitter junction and the collector junction is relatively low, and the resistance value measured by the other four connection methods is very high, about several hundred kilohms to infinity. However, whether it is low resistance or high resistance, the interelectrode resistance of the silicon triode is much larger than that of the germanium triode.

Meaning of letter codes for electronic components

Circuit board area is limited, in order to achieve better function and convenient maintenance, electronic components are usually in the form of alphanumeric code. In order to standardize electronic circuits and facilitate use, in general: the meaning of letter codes and numerical sequencing are certain rules.

Up! The gun for the price increase of electronic components continues to fire!

In 2017, the rising price wind blew from semiconductor silicon wafers, passive components, and MOSFETs all the way to resistors, aluminum electrolytic capacitors, and diodes. At the beginning of the new year, not only did Guoju and Lizhi Electronics raise the price of resistors, but Nijikang and Zhibao raised the price of aluminum electrolytic capacitors, and diodes could not escape the price increase. The price increase notice issued by Guoju on January 10 seems to have set the tone for the components industry in 2018. Today, aluminum electrolytic capacitors, resistors, MLCC and other markets have fired the price of the gun!
