sensors@ttelectronics.com | www.ttelectronics.com 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 recognized under UL file E58730. 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 Features: 15 kV dc electrical isolation Choice of phototransistor or photodarlington output Hermetically sealed LED and photosensor Base contact for conventional transistor biasing (OP120 only) UL recognized File No. E58730 Wide operating temperature range

If suitably encapsulated or oil-immersed, the isolation voltage is increased to 25 kV minimum. (2) UL recognition is for 15kV dc for one minute. (3) RMA flux is recommended. The duration can be extended to 10 seconds maximum when flow soldering. (4) Derate linearly 2.0 mA/°C above 25°C. (5) Derate linearly 2.67 mW/°C above 25°C. (6) Derate linearly 3.33 mW/°C above 25°C.
