Thyristors are a commonly electronic device, widely used in circuits such as frequency conversion speed regulation, power control, instantaneous constant power and other circuits.
When choosing a Suitable thyristor, the following aspects need to be considered.

1.Choose the appropriate voltage level according to the application scenario. The voltage level of a thyristor refers to the high operating voltage it can withstand. When selecting, it is necessary to determine the voltage level of the thyristor based on the working voltage of the circuit, and try to choose a voltage level slightly higher than the working voltage of the circuit to ensure reliability and safety.
2.Choose the appropriate current level based on the load current of the circuit. The current level of a thyristor refers to the operating current it can withstand. When selecting, it is necessary to determine the current level of the thyristor based on the magnitude of the load current. Generally, a current level slightly higher than the load current is selected to ensure reliability and stability.
3.Choosing a suitable thyristor should consider the forward voltage drop and turn off current of the thyristor. Forward voltage drop refers to the voltage drop of a thyristor in a conducting state. When selecting, it is necessary to determine the forward voltage drop based on the circuit operation’s voltage and power loss requirements, and try to choose thyristors with lower forward voltage drop to improve the efficiency of the circuit. Turn off current refers to the current of a thyristor in the off state. When selecting, it is necessary to determine the turn off current based on the circuit requirements. Generally, a thyristor with a smaller turn off current is chosen to reduce the power consumption of the circuit.
4.It is necessary to consider the triggering method and triggering current of the thyristor. There are two triggering methods for thyristors: voltage triggering and current triggering. When selecting, it is necessary to determine the triggering method and triggering current based on the circuit requirements to ensure that the thyristor can work properly. Thyristors, control trigger board, after triggering board,
5.We also need to consider the packaging form and working temperature range of thyristors. The packaging form refers to the appearance size and pin form of thyristors, generally including common packaging forms such as TO-220 and TO-247. When choosing, the form of packaging needs to be determined according to the layout and installation method of the circuit. The working temperature range refers to the temperature range where the thyristor can work normally, and generally there are common working temperature range such as -40 ° C ~+125 ° C. When choosing, you need to determine the working temperature range according to the environmental temperature of the circuit, and try to choose a thyristor with a wide range of working temperature to ensure reliability and stability.

In summary, selecting a suitable thyristor requires comprehensive consideration of factors such as voltage level, current level, forward voltage drop, turn off current, triggering method, triggering current, packaging form, and operating temperature range. Only by selecting appropriate thyristors based on specific application scenarios and requirements can the normal operation and stability of the circuit be ensured.
