What is MCT2?

This is a type of optocoupler, also known as an optoisolator. It consists of an LED and a phototransistor in a single package, and is used to transfer electrical signals between two isolated circuits.

Function: Optocoupler, Phototransistor

Package: DIP 6 Pin

Manufacturer: Fairchild Semiconductor

Pinouts:

Description

The MCT2 series optoisolators consist of a gallium arsenide infrared emitting diode driving a silicon phototransistor in a 6-pin dual in-line package. The LED and phototransistor are physically separated by a small gap, allowing the optocoupler to provide electrical isolation and protection against voltage transients and surges.

Features

1. Maximum collector-emitter voltage of 30 volts

2. Maximum collector current of 50 mA

3. Fast switching speed

4. Low power consumption

5. RoHS compliant

Description

The JC817 series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector. They are packaged in a 4-pin DIP package and available
in wide-lead spacing and SMD option.

A phototransistor is a type of transistor that is sensitive to light and is used as a light-sensitive switch. It is composed of a photosensitive material, such as a photodiode or a photogate, which is surrounded by a transistor that amplifies the electrical signal generated by the photosensitive material. The phototransistor can be used to detect light levels and changes in light intensity, making it a useful component in a wide range of applications, including optical communications, light detection and ranging (LIDAR), and optical touchscreens. Phototransistors are also commonly used in cameras, where they are used to detect light levels and adjust the camera’s exposure settings accordingly.
