Description:
Each Optoisolator in this data sheet contains an infrared Light Emitting Diode (LED) and a NPN silicon
Photosensor. The OPI120 has an 890 nm Light Emitting Diode (LED) and NPN phototransistor sensor, whereas
the OP123 has a 890 nm LED and a photodarlington sensor. The devices are sealed in a precast opaque housing
with a optically transmissive path between the LED and the photosensor.
The Optoisolators in this data sheet are UL approved under E 58730.
This series is designed for transmission of information between one power supply voltage to another where the
potentials during surge conditions are not greater than the guaranteed isolation voltage.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
TX and TXV processing is available. For more information, contact your local representative or OPTEK.
Applications:
• High voltage isolation between input
and output
• Electrical isolation in dirty environments
• Industrial equipment
• Medical equipment
• Office equipment
