The in every one's mouth development trend in photocouplers is targeting smaller packages, lower expense higher reliability, higher operating spe and lower power consumption, which corresponds with the requirements for electronic devices in the subsequent time

Defining the Photocoupler

The primary function of a photocoupler is to provide electrical isolation between the walls of an optical source. A photocoupler comprises the two a light emitting diode (LED) and a photodetector in common package. When a voltage (current) is applied, the L interchanges an electrical signal into an optical the same The photodetector receives the optical signal and changes it back into an electrical signal, forming an isolation interface in
