Optoisolators are a type of widely used electronic components used to isolate two circuits from each other. The OCP-PCT218/E model belongs to the optoisolators - transistor, photovoltaic output category. It is typically used for optical coupling of low-voltage and low-power circuits, including logic signals, timers, and digital controllers. It is a low-cost component, easy to install and it enjoys a wide range of applications.

The typical schematic of the OCP-PCT218/E is shown in the figure below. The OCP-PCT218/E optoisolator is mainly composed of an infrared LED, an integrated photoresistor and an NPN transistor. The LED provides light to the photo-resistor, and the current flowing through the LED is regulated by the photoresistor. The current is then applied to the base of the transistor, which can turn on or off the transistor. This is the working principle of the OCP-PCT218/E.

The OCP-PCT218/E supports a wide range of input and output voltages, from 3.3V to 5V, making it ideal for connecting two circuits of different voltages. In addition, the OCP-PCT218/E features a wide dynamic transmission range from 0.01lux to 1000lux, which makes it usable even in dark environments. Furthermore, the optoisolator is rated for a maximum output current of 500mA, a maximum collector-emitter voltage of 50V, and a maximum power dissipation of 750mW.

The OCP-PCT218/E is suitable for many applications, such as in low-voltage and low-power circuits, logic signals, timers, and digital controllers. It is also used in consumer electronics, smart meters, automotive electronics, communication systems, industrial controls, and factory automation. The optoisolator is especially useful in applications where high voltage isolation and noise suppression are required.

The OCP-PCT218/E is an example of an optoisolator - transistor, photovoltaic output component that provides electrical isolation between circuits. It offers a wide range of input and output voltages, a wide dynamic transmission range, and a maximum output current of 500mA. It is well-suited for a variety of applications in many different industries, such as consumer electronics, smart meters, automotive electronics, communication systems, industrial controls, and factory automation. This optoisolator is a great choice for anyone looking for a reliable and cost-effective way to electrically isolate two circuits.
