Thyristors - TRIACs

A TRIAC, or Triode for alternating current, is a type of thyristor device that can control both the direction and power of a current. It is mainly used in applications such as motor speed control and AC dimmers.

The OT337,116 is a four-terminal device that offers superior immunity to line applied transients and higher insulation voltage. It consists of two thyristors connected in antiparallel and also provides an integrated clamping diode.

Application Field

The OT337,116 is widely used for AC applications such as motor control, light dimmers, protection circuits and other AC switches. It can also be used for pulse-width modulation (PWM) applications that require precise control of the switching speed. It is also used in many other AC applications where tight regulation of the current is required.

In motor control applications, the OT337,116 can be used to smoothly adjust the speed of an AC motor. It can be used to control the output current during acceleration or deceleration, helping to reduce the stress on the load. It can also be used to control the voltage applied to the motor.

In light dimming applications, the OT337,116 can be used to regulate the brightness of an AC light. By varying the amount of power supplied to the light, the OT337,116 can be used to create a variety of lighting effects. It is also used in protection circuits to help ensure that devices are not damaged due to over- or under-voltage.

Working Principle

The OT337,116 is a bidirectional device and is designed to control the power and/or direction of an AC current. The device is made up of two thyristors connected in antiparallel, with an integrated clamping diode. The two thyristors are triggered by a control voltage, which can be either an increasing or decreasing voltage level.

When the control voltage is increased, the current will flow through the first thyristor, turning it on. The current will then flow out of the second thyristor, thus keeping it off. As the control voltage increases further, the current will eventually reach the breakdown voltage of the second thyristor, and it will turn on. As the control voltage increases further, the current will flow through both the thyristors, thus achieving the maximum current.

The OT337,116 is designed to handle a wide range of voltages, allowing for a wide range of current control. The device can also be used in reverse, allowing for reverse current flow. The device has a wide operating temperature range, making it suitable for many applications. The OT337,116 can also be used with a wide range of power sources, including both AC and DC.

In summary, the OT337,116 is a four-terminal thyristor device used for AC applications such as motor control and light dimming. It can be used to precisely control the current flow in AC and DC applications, providing many benefits such as improved performance, reduced stress on the load, and improved reliability.
