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.
The reasons for the inconsistent voltage drop of the four diodes in the rectifier bridge may be the following:
The diode mode is mainly used to measure the forward voltage drop of the diode, while the buzzer mode, also known as the on/off mode, is mainly used to measure the continuity of the circuit. Some multimeters combine the buzzer mode with the diode mode, while others separate these two modes.
A rectifier bridge typically consists of four electrodes, two of which are positive (Anode, marked as AC,~or arrow) and the other two are negative (Cathode, marked as -, - or circle).
Schottky diode is a special type of diode characterized by low voltage drop and fast switching speed.
