Optically Coupled Isolator OPI120, OPI123 Features: • • • • • 15 kV electrical isolation Choice of phototransistor or photodarington output Hermetically sealed LED and photosensor Base contact for conventional transistor biasing (OP120 only) UL recognized File No. E58730* Product Photo Here 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 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.
