Thyristors - SCRs - Modules

Thyristors (SCRs) Modules are electronic components used in a wide range of applications ranging from automotive to industrial control systems. The TD140N18KOFHPSA1 is a thyristor module manufactured by Waverock, an international leader in the electrical industry. It is a double-isolated thyristor module with both high speed and high current output.The TD140N18KOFHPSA1 module is designed for use in a variety of applications such as high-speed pulse-based control applications, motor control, industrial automation, photovoltaics, and more. The module offers a wide range of features, including: high speed input/output, built-in overvoltage protection, electrically isolated base, parallel connection of two or more of these modules in order to increase the current rating, and more.

Application Field

Thyristor Modules, such as the TD140N18KOFHPSA1, are widely used in a myriad of applications. Its wide range of features makes it suitable for high-speed pulse-based control applications, motor control, industrial automation, photovoltaics, and more. Specifically, high-speed pulse-based control applications can benefit greatly from the double-isolation feature that provides high speed input/output with superior overvoltage protection. This makes it an ideal choice for both military and medical applications.

Working Principle

The TD140N18KOFHPSA1 utilizes the concept of a Thyristor. A Thyristor is an electronic device that is designed to allow current to flow from a given point to another within a set voltage range. Specifically, the structure of a thyristor is composed of an anode (which is connected to the positive power source), a cathode (which is connected to the negative power source), and gate (which is used to trigger the flow of current).When voltage is applied to the gate, current starts flowing from the anode to the cathode. This process is called “turn on” and allows the current to flow until the gate voltage drops below a certain point. This point is known as the cut-off voltage. A reverse bias voltage then needs to be applied to the gate to turn off the thyristor and stop the current flow.Thyristors are useful in many applications, such as switching and control applications, motor control, and more. The TD140N18KOFHPSA1 module takes comfort the features of a Thyristor and adds an isolator to provide protection against overvoltage and other environmental conditions. This makes it highly suitable for various industrial and automotive applications, as well as many other applications.
