Thyristors are an important class of power semiconductor devices, with a wide range of application fields. One type of Thyristor is the Silicon Controlled Rectifier (SCR), which is a bidirectional device that can be used to switch any type of load or current. The ST1000C18K0 is a high-performance SCR manufactured by STMicroelectronics. This device is designed for use in a variety of electronic control and power conversion applications. It has excellent electrical performance, and is capable of switching up to 1000 A at 18 KV.

The ST1000C18K0 is a three-terminal device that has two gates and an anode. The two gates are used to control current flow through the device. The gates typically operate at ±2V or less, and can be driven by any suitable control circuit. A typical circuit diagram is shown in Figure 1.

The ST1000C18K0 SCR operates in two different modes, Forward Blocking (FB) and Reverse Blocking (RB). When in the FB mode, the device blocks current flow from the anode to the cathode, allowing only a minimal reverse bias current in the reverse direction. In the RB mode, the device blocks current flow from the cathode to the anode, but allows a higher reverse bias current. The FB mode is typically used for controlling turning on and off the load (e.g. motor applications) while the RB mode is typically used for power conditioning applications.

The ST1000C18K0 is an ideal device for a wide range of applications, including power conditioning, motor control, and other power conversion applications. It is capable of switching high currents at high voltages with minimal losses, making it an ideal choice for many power electronics applications.

The ST1000C18K0 is also highly reliable, with a low on-state voltage drop and low gate triggering voltage. It has a very low thermal impedance, so it can handle high power levels without the need for heat sinks. Additionally, it is designed to have a minimal gate leakage current, so it can be used in high-temperature applications. In summary, the ST1000C18K0 is a robust and reliable SCR for a wide range of electronic control and power conversion applications.
