T850H-6G Datasheet/PDFThyristors - TRIACs
The T850H-6G is one of the most popular Thyristors - TRIACs type of devices, which are used in many applications. They are used in motor control, power conversion, heating, lighting and many other applications.The T850H-6G is a three-phase, rated at a current of 6A.
Application Field
The T850H-6G is mainly used in applications such as variable-speed drive systems, adjustable-speed AC motors, adjustable-light-output dimmers, and AC power sources. It is widely used in controlling the speed and power of a motor. It can also be used for controlling the light output of a lamp or a dimmer, as well as for controlling the power of an AC source. In addition, it can be used in lighting, heating, air conditioning, audio-visual systems, medical equipment, and many more applications.
Working Principle
The T850H-6G has three terminals, two on the bottom of the body (mainly called main terminals or main gate) and one on the top (called the auxiliary terminal or gate). The main and auxiliary terminals act in conjunction with each other, allowing for control and modulation of the output. The power flow is in the reverse direction, which means that when the control signal is applied to the gate terminal, it can turn the device ON and allow the current to flow in the opposite direction. When the control signal is removed, the gate is OFF and the current stops flowing.
The two main terminals are designed to be AC-isolated, which means that the T850H-6G can be used in systems with AC power. The use of this device in AC systems also provides the benefit of self-protection features, as it is designed not to be damaged when exposed to over-currents or other dangerous conditions.
The T850H-6G can also be used in DC applications, allowing for the control and modulation of the power flow. To use this device in a DC circuit, it needs to be connected in either a “normally closed” or “normally open” configuration. In this configuration, the T850H-6G control terminals can be used for controlling the polarity and direction of the power flow. By adjusting the voltage to the gate, the current through the device can be controlled.
The T850H-6G is a very versatile device and can be used in many applications. It is easy to avoid malfunction and damage to the device by following the manufacturer’s instructions and using the correct power ratings. It is always important to consider the environment the device is used in and its highest current ratings, as it is more prone to malfunction and damage when overloaded.
