Power diodes and ordinary diodes are two different types of diodes with different structures and characteristics.
With the upgrading of consumer electronics functions and the continuous increase in usage in the new energy vehicle manufacturing industry in recent years, the demand for upstream passive electronic components such as surface mount diodes has gradually increased. Especially after strong support for the development of new energy vehicles, the market's demand for surface mount diodes and voltage regulator electronic components has become even greater.
The band gap of silicon carbide is 2.8 times that of silicon (wide bandgap), reaching 3.09 electron volts. Its insulation breakdown field strength is 5.3 times that of silicon, up to 3.2MV/cm, and its thermal conductivity is 3.3 times that of silicon, at 49w/cm · k.
When using a voltage regulator, we need to pay attention to the following aspects. Firstly, it needs to be reversed in the circuit to stabilize the voltage. That is to say, the negative pole of the voltage regulator is connected to the high potential in the circuit, and the positive pole is connected to the ground potential. If it is reversed, it will burn out the voltage regulator due to excessive current.
Silicon carbide is an inorganic substance with the chemical formula SiC. It is produced by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt needs to be added when producing green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite.
TVS (Transient Voltage Suppressor) tube, also known as Transient Voltage Suppressor diode, is a new type of high-efficiency circuit protection component invented on the basis of Zener diode technology. The core advantages of TVS tube are p-second response time and high surge absorption ability.
