JC817

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.

PS2501 photocoupler

Description

The PS2501, -1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode and an NPN silicon phototransistor. The devices are in a plastic DIP (Dual In-line Package) and the PS2501L-1, -2, -4 are lead bending type (Gull-wing) for surface mount.

A photocoupler, also known as an optocoupler or an optical isolator, is an electronic component that provides electrical isolation between two circuits while allowing them to communicate with each other optically. It typically consists of an LED and a photodetector, such as a photodiode or a phototransistor, housed in a single package. The LED transmits an optical signal to the photodetector, which converts it into an electrical signal that can be used to trigger or switch another circuit.

The isolation provided by a photocoupler makes it useful for applications that require electrical isolation for safety reasons, such as medical equipment or industrial control systems. It also helps to reduce noise and interference in sensitive analog circuits, and can protect sensitive microcontrollers and other digital circuits from high voltage transients.
