Thyristors - TRIACs

A Triac, with its acronym derived from Triode for Alternating Current, is a type of thyristor that can control both directions of current. The T1235H-6G-TR is one of the most popular models of Triac and is used in many applications due to its wide range of features. In this article, we will explain the application field and working principle of the T1235H-6G-TR.

Application Field

The T1235H-6G-TR model is especially useful in applications requiring high power switching and dimming capabilities. It can be used in a wide range of consumer and commercial equipment such as medical equipment, lighting controls, home appliances and HVAC systems, just to name a few. This device can be used in either alternating current (AC) or direct current (DC) circuits and is capable of switching power up to 540mA and 300V.

Working Principle

The T1235H-6G-TR is a four layer, bidirectional Triac that works by connecting an anode to a gate and a cathode to another gate. This allows it to pass current in both directions when activated and can be used to switch current on or off. The T1235H-6G-TR has two separate gate pins, one for each direction. The voltage applied to these pins must be higher than the rated gate trigger voltage for the device to be activated and will continue to control the current until the currents drop to zero.

This Triac is also capable of phase-control dimming, which is a type of dimming method used to control the brightness of lights. This is done by controlling the amount of current that passes through each half-cycle of an AC wave, resulting in the average current output for each half-cycle being decreased. This reduces the total power output and results in the lights being dimmer.

Conclusion

The T1235H-6G-TR is a popular Triac and is used in many different applications such as consumer and commercial equipment, lighting controls, and HVAC systems. Its two-way switching capabilities make it especially useful for switching larger amounts of power and its phase control dimming features make it ideal for dimming applications.
