In order to correctly select thyristor components, it is necessary to understand their main parameters. Generally, the average or limit values of the parameters are provided in the product catalog, and the measured data of the components are marked on the product certificate.
Light controlled thyristor, also known as GK type optical switch transistor, is a type of photosensitive device.
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.
