CM431690 is a module produced by a reputable electronic component manufacturer, specifically designed for switching, regulating and controlling circuits. It is composed of of a high power thyristor plus a cascode gate. This product is housed in a 12-lead TO-263 package which features a positive temperature coefficient, low thermal resistance, low cost, and minimal inductance, making it an ideal choice for inverters and similar applications requiring high DC current.

The CM431690 is a full-controlled miniature phase-control thyristor module, with a rated voltage of 600V and a rated current of 17A (max). It is designed to be able to switch, control and regulate electrical circuits with minimal losses and high efficiency. The module also features a reverse blocking capability, and is capable of handling surge voltage applications.

The working principle of the CM431690 module is based on a thyristor plus a cascode gate. This means the thyristor gate drive circuit is isolated from the anode voltage of the device, allowing for high surge capability, and improved dv/dt stability at high operating temperatures. The thyristor inside the module is constructed from a junction gate field effect transistor (JFET) and a silicon controlled rectifier (SCR).

The JFET and SCR are connected in series, with the JFET being used to control the opening and closing of the device. When the JFET is switched on, the SCR turns off and no current can flow through the circuit. Conversely, when the JFET is switched off, the SCR turns on, permitting electrical current to flow. This allows the module to switch, regulate and control the input current, thus controlling the output voltage.

The CM431690 module is widely used in applications ranging from commercial to industrial. It has a wide range of applications, such as AC/DC motor drives, DC voltage regulation, UPS systems, liquid level controllers, rectifiers, inverters, and power converters. Thanks to its high power rating, it can also be used in larger industrial applications, such as photovoltaic systems, wind turbines, and even electric vehicle propulsion systems.

In short, the CM431690 module is an excellent choice for those requiring a reliable, cost-effective, and high-power thyristor solution for switching and regulating electrical circuits. Its simple yet reliable design makes it suitable for both commercial and industrial applications, providing reliable switching and regulation of electrical current.
