OPI123

Optically Coupled Isolator OPI120, OPI123 Features:  15 kV dc electrical isola on  Choice of phototransistor or photodarlington output  Herme cally sealed LED and photosensor  Base contact for conven onal transistor biasing (OPI120 only)  UL recognized File No. E58730  Wide opera ng temperature range Description: Each Optoisolator in this data sheet contains an infrared Light Emi ng Diode (LED) and a NPN silicon Photosensor. The OPI120 has an 890 nm Light Emi ng Diode (LED) and NPN phototransistor sensor, whereas the OPI123 has a 890 nm LED and a photodarlington sensor. The devices are sealed in a precast opaque housing with a op cally 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 informa on between one power supply voltage to another where the poten als during surge condi ons are not greater than the guaranteed isola on voltage. Custom electrical, wire and cabling and connectors are available. Contact your local representa ve or OPTEK for more informa on. Applications: High voltage isola on between input and output Electrical isola on in dirty environments Industrial equipment Medical equipment Office equipment Ordering InformaƟon Part Number LED Peak Wavelength OPI120 890 nm or 935 nm OPI123 Sensor IsolaƟon Voltage (,000) Transistor Darlington CTR Min IF (mA) Typ / Max 20 15 50 10 / 50 VCE (Volts) Max Lead Length / Spacing 25 0.40" / 0.75" 20 RoHS General Note TT Electronics reserves the right to make changes in product specifica on without no ce or liability.
