T835H-6G-TR Discrete Semiconductor Products

Thyristors - TRIACs

The T835H-6G-TR is a 3-terminal Triac semiconductor switch that is part of the larger Triac family of triggerable AC switches. This type of switch is designed to control large currents, such as those found in electric motors, heaters, drivers, etc. It is commonly used in thermostats and other building automation systems.

Application Field

The T835H-6G-TR is best suited for applications where large amounts of power need to be switched on and off quickly and safely. The device is especially useful for controlling electric motors, as it can switch several hundred volts at a few amps without danger of sparking. It is also used in many industrial applications as, for example, power supplies, motor controls, home automation and other energy management systems.

Working Principle

The design and operation of the T835H-6G-TR follows the Triac family standard. The device brings together two parallel thyristors, or SCRs, into a single package. This is done by having each thyristor connected to one terminal of the switch and the third terminal being the common connection between these two thyristors. When the switch is activated, the two thyristors are triggered in tandem and therefore current is allowed to flow through the Triac switch.

The current that passes through the switch is determined by the amount of current that passed through the trigger terminal. This means that by controlling the current in the trigger terminal you can control the amount of current that flows through the device. The current in the trigger terminal can be supplied externally, or the device can be triggered by a low-voltage signal.

The T835H-6G-TR also features an integrated snubber circuit that helps minimise distortion caused by high-frequency thyristor switching. This is an important feature as it helps to ensure that the AC waveform remains consistent and prevents any potential detrimental effects due to current or voltage spikes.

Conclusion

The T835H-6G-TR is a useful and reliable device that finds its way into a range of applications and devices. Its simple yet effective design makes it a great choice for controlling large AC loads in a safe and efficient manner. The integrated snubber circuit helps minimise any distortion caused by the device and helps ensure that the AC waveform remains stable.
