Thyristors - TRIACs : T835H-6T application field and working principle

Thyristors are solid-state switching devices used for switching power between two terminals. Thyristors come in different shapes and sizes and have different ratings. One such thyristor is the T835H-6T. It is designed for switching AC power and is known as a Triacs - a three terminal ac switch.

The T835H-6T has a robust package that stands up to harsh industrial environments. It has an operating temperature range of -40 to +125°C, and a nominal current rating of 6 Amps. It is ideal for use in illumination, household appliances, and heating control applications.

The T835H-6T is commonly used in lighting and heating applications because of its ability to switch a high current load with a low voltage between power terminals. The device\'s working principle is based on the use of a thyristor to switch the power from a low voltage to a higher current. When a positive voltage is applied to the gate terminal, it amplifies the voltage applied to the anode, thus turning on the thyristor.

The T835H-6T also has an on-state voltage (or breakover current) characteristic, where a small voltage is all that is required to turn on the device. Once the breakover current is reached, current will travel through the device, activating the gate electrode and causing the device to turn on. This allows the device to remain in the on-state until the current is turned off by either the user or the device itself.

It is important to note that while the T835H-6T can handle a high current, it must still be operated within its ratings to avoid overloading. Failure to do so could damage the device and cause it to fail, leading to dangerous and potentially dangerous situations. It is also important to understand the functionality of the thyristor before applying it in any application.

Overall, the T835H-6T is an ideal choice for applications requiring the switching of a high current load between AC terminals. Its robust package provides reliable performance in harsh environments, and its low voltage requirement for turn on makes it suitable for use in lighting and heating control applications. Understanding its working principle and operating within its ratings should help ensure safe and reliable operation.
