Thyristors are a type of semi-conductors which are used in a wide array of applications. The MCD700-20IO1W module is a specific type of thyristor that has been designed for high performance applications including motor control, power conversion, and general purpose switching. This article will explain the application field and working principle of the MCD700-20IO1W.

The MCD700-20IO1W module is mainly used in applications that involve high power and/or high voltage. This module is capable of controlling currents up to 700A, making it ideal for applications that require high power. It is also capable of operating at high voltages of up to 750V, making it suitable for applications such as motor control, power conversion, and other general purpose switching applications. Furthermore, the MCD700-20IO1W has an isolation rating of 1500V RMS, which makes it suitable for applications that require high reliability and safety.

The MCD700-20IO1W is also suitable for applications that require fast switching, as it has a gate charge of only 1nC. This makes it possible for the module to be used in a range of time-critical applications, such as motor control, power conversion, and general purpose switching. Additionally, the MCD700-20IO1W has a very low on-state voltage drop, meaning it can be used in applications in which power efficiency is important.

The working principle of the MCD700-20IO1W module revolves around the application of a gate voltage. This voltage, usually between 2.8 and 3.2V, acts to forward bias the gate-cathode junction, allowing current to flow between the anode and the cathode. Once enough current flows, the thyristor is triggered, setting the voltage across the rectifier to the threshold voltage of around 1.2V. From this point the thyristor will remain switched on until the current drops below a certain level.

In order to turn off the thyristor, the gate voltage must be reversed and the current must be removed. This is done by briefly reducing the current so that the current falls below the holding current, which is the minimum current required to keep the MCD700-20IO1W in the on-state. Once the current has been reduced, the thyristor will turn off, effectively ending the switching cycle.

Overall, the MCD700-20IO1W module is a versatile thyristor which can be used in a wide range of applications. Its features make it suitable for applications requiring high power, high voltage, fast switching, and power efficiency. Its working principle revolves around the application of a gate voltage, which triggers the switching cycle. With its high performance capabilities and low on-state voltage drop, the MCD700-20IO1W is a great option for high-power applications such as motor control, power conversion, and general purpose switching.
