C438N

Thyristors - SCRs, also known as silicon-controlled rectifiers, are four-layer, three-terminal semiconductor devices. Thyristors - SCRs are normally used as switches to control current in high voltage AC power distribution circuits. These devices are ideal for applications where high reliability and resistance to the environment are required. They are fabricated from silicon, which makes them reliable, cost-effective and easy to use. They have a wide range of applications and are used for controlling voltage and current in applications such as switching power supplies, motor controls, lighting controls, solar power systems, and other industrial control systems. The main benefits of these devices is their high efficiency, low-voltage drop, and fast switching capability.

A C438N SCR is a type of thyristor - SCR with a low current capacity of 10A, a high voltage rating of 800V, and a static and dynamic on-state resistance of 12 mOhms. It has four terminals, two gate (G1 and G2) and two anode and cathode. C438N SCR has a blocking voltage rating of 800V, which makes it suitable for high voltage applications. This device is typically used to switch AC power in solar panel applications, motor controls, and inverters.

C438N SCR can be used in applications such as motor control, lighting control, UPS, and other applications in which AC power needs to be switched. Its characteristics make it a suitable choice for applications in which high voltages and high currents are present. In motor control applications, C438N SCR can be used to switch currents up to 10A, allowing for the control of high torque motors. In solar panel applications, the C438N SCR can be used to control the voltage and current in a solar power system, ensuring greater efficiency of the system. In lighting control, the C438N SCR can be used to switch LED lights in a dimming system, allowing for adjustable lighting levels.

The working principle of C438N SCR is based on the PNPN switching action. When a control signal is applied to the gate terminal, the SCR turns ON and passes an alternate current. The current will remain in the ON state until the current is cut off or the signal at the gate terminal is removed. The C438N SCR has a fast control gate, which increases its switching speed, making it more suitable for high-speed applications. When the gate voltage is removed, the SCR turns back OFF, and the current is cut off.

C438N SCR offers many advantages over conventional thyristors due to its small size, high efficiency, and low cost. Its small size makes it suitable for high-density applications and its high efficiency reduces power losses. Its low cost also makes it a suitable choice for applications where cost is an important factor. The C438N SCR is an ideal choice for applications in which AC power needs to be switched with high efficiency and reliability.
