Application Field and Working Principle of TC20402402DH

Introduction

TC20402402DH is a semiconductor device belonging to the Thyristors-SCRs-Modules family. It is used to turn current in one direction, being suitable for many different applications. It can be used in an alternating current (AC) or DC circuits, and it is specifically designed for the power semiconductor market.

Application Field

This device is mainly used for power control of AC and DC motors, power supplies, inverters, appliances, and other applications related to energy control. It provides a high power control, with low power dissipation, making it ideal for applications where a high power is required with reduced size components. It can also be used as part of a reversing starter function, allowing the user to start and stop the motor according to its needs.Also, this semiconductor device is used to make rectifiers and power supplies, since it is able to withstand the high voltages and currents required by these devices. Furthermore, it can be employed in automotive control systems, such as ignition systems, in order to improve their efficiency. In addition, it can be used to build a full range of applications, including overload protection, current sensing, voltage limitation, sound alarm, etc.

Working Principle

The TC20402402DH is a compound structure made up of two serially connected stationary gate controlled thyristors. This arrangement provides a full-wave rectifier output, by combining two anti-parallel thyristors switching in pairs. When the TC20402402DH is connected in place and activated, the energy applied to the gate circuit of the thyristor starts to flow, provoking the first thyristor to become activated. This turns on the second thyristor, which triggers the current flow in the opposite direction. This process of on-off switching continues to alternate during the operation of the semiconductor device, allowing the current to pass through it and be regulated as desired.

Advantages

The TC20402402DH is a very efficient and reliable semiconductor device, since it is able to withstand high power levels and stand severe conditions of operation, such as very low and very high temperatures. It also features excellent creepage and clearance parameters, protecting it from voltage breakdown and arc-over. Furthermore, it has been designed to provide a low on-state voltage drop, making it more efficient than other thyristors. Finally, it is very easy to install and use, due to its lightweight, compact size, making it ideal for small applications where space is limited.

Conclusion

The TC20402402DH is an extremely versatile semiconductor device, suitable for many different applications. It has been designed to provide a high power regulation with low power dissipation, making it one of the most efficient thyristors on the market. It is also very reliable and easy to install, due to its compact size, allowing it to be used in small spaces. Finally, it features high creepage and clearance parameters, making it ideal for high voltage applications. With all these features, the TC20402402DH is the perfect choice for any type of power control application.
