Thyristors – TRIACs

A thyristor is an electrical component that, in most cases, passes current only in one direction. Thyristors are also known as solid state switches and they have their own applications in many industries and projects. There are various types of thyristors available and one of them is the TRIAC, which stands for Triode Alternating Current. In this article we will look at the CTA16-1200CPT application field and working principle.

CTA16-1200CPT Application Field

The CTA16-1200CPT is a TRIAC with a maximum current rating of 1200A at 600V AC. It is ideal for applications that require very high current rating and low on-state voltage drops. It is typically used for controlling high power loads in industrial and residential applications, such as electric motors, solid state relays and electric heating systems. This TRIAC is suitable for high frequency operation, making it an ideal choice for motor control applications.

CTA16-1200CPT Working Principle

This TRIAC works on the principle of opto-coupling. When the voltage across the control terminals is greater than the set threshold voltage, the TRIAC turns on and stays on until the current reduces to a certain level. This TRIAC can also be triggered using an external signal, such as a pulse, making it ideal for PWM applications.

A key feature of this TRIAC is its very high dissipation capability. The CTA16-1200CPT is designed to dissipate up to 800W during high current operation, enabling it to handle large power loads. Moreover, the device offers a fast turn-on time, allowing for very high switching frequency applications.

The CTA16-1200CPT is available as a surface mount package, making it suitable for both high-volume applications and OEMs. It is also highly reliable, making it an ideal choice for use in automotive and industrial applications.

Conclusion

This article has looked at the CTA16-1200CPT application field and working principle. It is a TRIAC with a maximum current rating of 1200A and an on-state voltage drop of just 0.5V. It is designed to handle high power loads and offers very high dissipation capability, making it ideal for industrial and residential applications. The device is also highly reliable and is available as a surface mount package, making it suitable for both high-volume applications and OEMs.
