Thyristors - SCRs (Thyristor-Controlled Rectifiers) are semiconductor devices that act as electronically-controlled switching elements. The S4004VS2TP is one type of SCR, which is characterized by its ability to control high power using a low power signal and offering a unique combination of high electrical efficiency and superior temperature and AC power cycling performance. This article will discuss the application fields and working principles of S4004VS2TP.

The application fields of S4004VS2TP mainly include to AC and DC motor controls, renewable energy, electric vehicle battery charging, HVDC electric power transmission, welding, data centers and other battery backup systems. Specifically, S4004VS2TP is well suited for controlling switching of loads such as served motors, pumps, integrated electric motors, large heaters and home appliances, induction motors with solar inverters, and latching relays.

The working principle of the S4004VS2TP is based on its properties of a pass transistor, which triggers with low gate current and low gate voltages, providing a low-power electronic switch. In addition, S4004VS2TP SCRs are capable of controlling high power using low-power signals, with a unique combination of high electrical efficiency and superior temperature and AC power cycling performance. This control is based on the principle of reverse conducting mode (RgCm) of the device.

The RgCm operation model of the S4004VS2TP involves a two-terminal thyristor, referred to as the Gate-Controlled Terminals (GCTs). When a forward trigger voltage is applied to the GCTs, the S4004VS2TP will start to conduct current. The RgCm operation model takes advantage of the GCTs to reduce the overall power loss of the device. Through the body-diodes of GCTs, the current can be reversely conducted, and the resulting circuitry is named Reversed-Conducting Mode (RgCm). This greatly reduces the power losses in the device.

In short, the S4004VS2TP SCR is an extremely reliable semi-conductor device for controlling high power using a low power signal. It is capable of controlling switching of loads such as AC and DC motors, renewable energy, electric vehicle battery charging, welding, data centers and other battery backup systems. It has a unique RgCm operation model, which helps reduce the overall power loss of the device. Thanks to a combination of high electrical efficiency and superior temperature and AC power cycling performance, the S4004VS2TP can be used for various applications and for a variety of purposes.
