Optoisolators, also known as optocouplers, are devices used for electrical isolation. They provide a high degree of electrical separation between the input and output by using a light beam to transport the signal. The OCP-PCTB116/E-TR is a 4 Pin, Transistor, Photovoltaic Output Optoisolator.

The OCP-PCTB116/E-TR optoisolator consists of a gallium arsenide infra-red LED (Light Emitting Diode) and a silicon NPN phototransistor. When activated, the LED transistor emits a light beam that switches on and off the corresponding NPN phototransistor. Connections to the PCB board (Printed Circuit Board) are in a 28DIP (dual in-line package).

This optoisolator is used in applications such as printer control boards and power controllers, motor control circuits, security systems, industrial and consumer communication, automotive controllers, pulse transformers and digital displays. It is also used in medical diagnostics, solid-state relays, modems and industrial CCTV. The optoisolator is widely used in the industrial sector and in home automation systems.

The OCP-PCTB116/E-TR has a maximum electrical isolation voltage of 8kV which makes it suitable for applications that require very high levels of isolation between the input and output. It can be used in circuits with a wide range of power supplies, and it can operate from a wide range of supply voltages. The LED can handle up to a peak current of 20mA.

The working principle of this optoisolator is based on the phenomenon of photoelectric effect. It works by passing a beam of light from the LED to the output transistor which is switched on and off by the light signal. This creates an electrical signal that is sent to the output. The LED used in this optoisolator has a reverse voltage of 5V and a forward voltage of 1.2V. The output transistor has an on/off gain of between 100 and 1000.

The OCP-PCTB116/E-TR optoisolator is a reliable device that provides electrical isolation and protection in difficult environments. It is a cost-effective solution for applications that require electrical isolation, such as in industrial and consumer electronics. The optoisolator can also be used in motor control circuits that need to switch high currents. It has a compact design and a low cost, making it an attractive choice for a variety of applications.
