Thyristors, also known as Silicon Controlled Rectifiers (SCRs), are power devices used for control and protection in power systems. They have been used for decades to ensure trouble-free operation and accurate control. The C158M is a type of thyristor specifically designed for general purpose applications.

The C158M is a three-terminal power device and uses two extra terminals, gate and cathode, to control the current. The device acts as a switch that is normally closed and opens when a current is applied to its gate terminal. This makes the C158M suitable for use as a switch in applications requiring precise timing and control.

In applications where precise current control is required, C158M can be used as a voltage-controlled switch. The device can be configured to respond to changes in the control voltage and can be used to limit the maximum current passing through the system. This makes it ideal for switching applications that require precise control of the current passing through them.

The C158M is also used for protection applications where the thyristor acts as a crowbar to protect the circuit against excessive current. In such a configuration, the C158M will detect any overcurrent and quickly switch off the entire circuit, thereby protecting the system from damage.

The C158M also has the advantage of being able to detect small temperature changes, allowing it to be used in temperature control applications. In temperature control applications, the C158M is usually connected to an external microcontroller. The microcontroller then uses the data from the C158M to adjust the output current to maintain a constant temperature.

In summary, the C158M is a versatile silicon controlled rectifier that can be used in a variety of applications. It is used to control and protect power systems, as well as to provide precise control and protection in switching, overcurrent protection and temperature control applications.
