Optoisolators, as their name implies, are electronic devices that use light generated by a light source to interface between two circuits to isolate them with an optical waveguide. The TLP2166A(TP,F) is an opto-isolator logic output type that applies a two-channel input from an external power source and provides a logical output to the output side of the device, thus serving as an electrical isolation barrier. The TLP2166A(TP,F) optoisolator has a low forward current rating of 5mA, and can be used in medium to high voltage applications.

Structure and Working Principle:

The TLP2166A(TP,F) optoisolator consists of a photodiode, an LED, connecting wires, an output transistor, and a protective diode. The structure of the device can be viewed in figure 1. When light from the LED passes through the waveguide, it is then detected by the photodiode. The current produced by the photodiode is passed to the output transistor and energizes it. This in turn causes the output transistor to produce a current that flows to the output device. In this manner, the TLP2166A(TP,F) optoisolator acts as an electrical isolation barrier between the two circuits, providing a low-power output signal.
