Thyristors

TRIACs

A TRIAC (triode for alternating current) is a three-terminal electronic switching device that is mostly used to switch alternating current (AC). It is a 20th-century alternative to the two-terminal low-current devices such as relay contacts, incandescent light bulbs, and thyratrons that were used to control AC. TRIACs are widely used in applications such as controlling lamp brightness in modern dimming systems, controlling the speed of motors, and many other applications.

Q6012LTH1LEDTP Application Field and Working Principle

The Q6012LTH1LEDTP is a 800V thyristor designed for a range of 400V to 570V phase control applications. It has a low on-state voltage drop for superior power efficiency and is suitable for light-dimming applications. It is suitable for hot switching at the input point of an AC motor drive or other motor control applications.

The Q6012LTH1LEDTP thyristor consists of a pair of PN junction connected by a strip of gold metal in a U-shaped, or "crowbar," configuration. When the terminal, called the gate, is connected to a positive voltage source, it induces a current flow between the two PN junctions, producing an "on" state.

When the gate voltage is removed, the thyristor enters the "off" state and there is no current flow through the device. This characteristic makes the thyristor an excellent candidate for applications requiring the on/off control of AC power such as light dimmers, motor drives, and other AC relay applications. The thyristor is designed to take up to 800V, making it suitable for use in many high voltage applications.

The thyristor is also designed with a protection diode at the gate terminal to protect the device from transient voltage and current surges. The diode prevents the thyristor from entering the "on" state when the gate voltage is not high enough. This ensures the reliability and safe operation of the device.

The thyristor also has a built-in temperature sensor at the gate terminal which will shut off the thyristor if the temperature of the device goes beyond the designed limit. This will prevent the device from entering a thermal runaway situation and ensures its safe operation.

In summary, the Q6012LTH1LEDTP thyristor is an ideal choice for applications requiring accurate, fast and precise control of AC power. The built-in protection diode and temperature sensor ensure the safety and reliability of the device.
