SFH615A-2X016 application field and working principle

Optoisolators - Transistor, Photovoltaic Output, SFH615A-2X016 is a specialized type of Opto isolator, also referred to as a photocoupler or an optocoupler, designed to provide electrical isolation between the input and output of two circuits. This is achieved by transmitting electrical power across an air gap or a vacuum, using light waves to form a communication "bridge".

Opto-isolators SFH615A-2X016 are designed to provide increased reliability in applications subjected to EMI, RFI, static discharge, voltage spikes and other noise on the input. In addition to providing isolation, opto-isolators are primarily used to extend the life of equipment or to allow for control of hostile loads. The SFH615A-2X016 isolator features an a Selective Metal-Oxide photo-semiconductor (MOS) optically coupled LED to a transistor output and is built in a 5-pin DIP package.

The working principle of the SFH615A-2X016 opto-isolator is based on a LED and a semiconductor photo-detector. This opto-isolator has data electrical isolation of at least 8 kV and offers 1 A of maximum sinking capability. Light emitted by the LED is coupled through a sealed transparent polycarbonate disc and focused on a photo-diode. When the diode absorbs the light, it issues current in proportion to the intensity of light. This current in the photodiode is then transferred to the output transistor to control the output.

SFH615A-2X016 is widely used in industrial field such as, Motor Drives, Servo Control, Power Supplies, Start/Stop Controllers, Test Equipment, Data Acquisition Systems, Automated Assembly, and as an interface to high voltage equipment. The major benefits of optoisolators such as its SFH615A-2X016 can provide an electrical connection with no need for wires or cables, the extended life of equipment, the improved accuracy of control, and the extended operational life of the equipment due to its ability to reduce noise on the input.

In conclusion, the SFH615A-2X006 opto-isolator is a great choice for industrial applications because the superior design features of the device help to extend the life of the equipment, improve the accuracy of control, and reduce the noise on the input. The working principle of the device ensures that the output is controlled by a current instead of voltage, providing complete electrical isolation and improving system reliability.
