For the safe use of field-effect transistors, the maximum dissipation power, maximum drain source voltage, maximum gate source voltage, and maximum current of the transistor should not be exceeded in the design of the circuit.
Zener diode (also known as a Zener diode) is a surface junction silicon semiconductor diode manufactured using a special process.
The quality of field-effect transistors can be easily judged using a multimeter The method is to use a multimeter to measure the resistance value between the electrodes of the field-effect transistor, and then compare it with the resistance value indicated in the manual.
Under normal circumstances, there is only a very small current in a reverse biased PN junction. This leakage current remains constant until the reverse voltage exceeds a specific value, after which the PN junction suddenly begins to conduct with a large current.
The application range of diodes is very wide. As long as diodes have unidirectional conductivity, they can be used for rectification, limiting, protection, detection, clamping, and switching circuits. The following mainly introduces the applications of diodes in several aspects.
A P1N1P2N2 four layer three terminal device based on silicon single crystal, created in 1957. Due to its characteristics similar to vacuum thyristors, it is internationally known as silicon crystal thyristors, abbreviated as thyristors.
