PhotoMOS® technology

Relay: PhotoMOS Technology Panasonic Industry

The basic construction of the PhotoMOS® relay can be seen in the illustration. Light emitted from an LED on the input side passes through an isolator that is permeable to light and is detected by a solar cell. Via a trigger circuit, the solar cell‘s output voltage controls the gates of two source-coupled MOSFETs at the output. This arrangement allows PhotoMOS® relays to switch both AC and DC loads. The integration of MOSFET technology in PhotoMOS® relays significantly differentiates them from semiconductor relays with triacs or transistors at the output.
