TLP168J(U,C,F) Optoisolators - Triac, SCR Output Application Field and Working Principle

An optoisolator is an electrical component that isolates the input side of a circuit from the output side of a circuit. The TLP168J(U,C,F) optoisolator is a type of optoisolator with a Triac or SCR (Silicon Controlled Rectifier) output. It is ideal for controlling the outputs of both AC (Alternating Current) and DC (Direct Current) circuits, including audio and signal processing. It is also designed for industrial applications in fields such as motor speed control, temperature control, and motor/actuator control.

This optoisolator is composed of an optocoupler and a pair of solid-state switching networks. There are two main parts of the device: the optocoupler and the solid-state switching networks. The optocoupler includes a low-current diode, a photoresistor, and a current limiting resistor, and its main function is to convert an input signal into an optical signal. The two solid-state switching networks serve to switch the inputs and outputs of the circuit. The overall design of the device provides an electrical isolation between the input side and the output side of the circuit, allowing two circuits to communicate without any direct electrical contact.

In terms of applications, these optoisolators are often used to control the outputs of AC and DC circuits. For example, equipment in motor speed control and temperature control require accurate control of the circuit outputs, and this optoisolator provides a safe and stable way to do this. The optoisolator also features wide operating temperature range, making it suitable for applications in extreme environments.

In terms of its working principle, the functioning of these optoisolators is based on the conversion of an electrical signal into an optical signal. To achieve this, when an electrical input signal is applied to the device, the low-power diode in the optocoupler is turned on. This emits a light beam that is received by the photoresistor, triggering an electrical output signal. This output signal is then sent to the two solid-state switching networks for conversion into the required output signal.

The TLP168J(U,C,F) optoisolator is a high-performance device that provides reliable electrical isolation between the input side and the output side of the circuit. It is ideal for controlling the outputs of both AC and DC circuits in industrial applications, particularly those in motor speed control, temperature control, and motor/actuator control. Its main working principle is based on the conversion of an electrical signal into an optical signal using the optocoupler, followed by the conversion of this optical signal into the desired output signal using the two solid-state switching networks.
