Thyristors, also known as Silicon Control Rectifiers (SCR) or Triac, are a class of semiconductor devices commonly used in power electronics applications. The SMP100LC-35 is a type of thyristor, used to regulate the voltage and power flow in low-voltage direct current (DC) systems. Thyristors are one of the most widely used power electronic devices, as they can easily control the magnitude of power in a circuit, as well as rectify alternating current to direct current.

The SMP100LC-35 is designed for low breakdown voltage applications, and features an integrated overvoltage protection circuit. This circuit reduces the power supply current level by reducing it when the voltage exceeds a certain limit. This helps protect the circuit from over-voltage, short-circuit, over-current and over-heating effects. Additionally, this device can be used to regulate the current in an AC supply. It also has a low loss current-limit, which helps to ensure that the voltage and current levels in the system remain within a safe range.

The working principle of the SMP100LC-35 is based on the switching action of the thyristor. When the voltage level reaches a certain threshold, the thyristor turns "on", allowing current to pass from the supply to the load. When the load is no longer active, the thyristor shuts off, effectively disconnecting the load from the supply. This switching action can be used to regulate the power in the circuits, for example, by limiting the amount of power that is drawn from the supply, or by regulating the current in an AC circuit.

The SMP100LC-35 thyristor is typically used in low-voltage DC applications such as solar PV panels, battery charging systems, DC motors, and LED lighting. It can also be used in AC applications, such as in HVAC systems, industrial automation, and adjustable frequency drives. Additionally, the integrated overvoltage protection circuit makes it well-suited for applications in which inrush current or over-voltage is a concern.

The SMP100LC-35 thyristor is a versatile and reliable device for low-voltage DC and AC applications, and its integrated overvoltage protection circuit adds an extra layer of protection against electric shock and other hazards. With its ability to regulate power in both DC and AC systems, as well as its ability to turn "on" and "off" quickly and reliably, this thyristor is an ideal choice for many applications.
