Optically Coupled Isolator / High Speed Optically Coupled Isolator
OPI150, OPI153, OPI155
Features: • 50 kV electrical isolation • Choice of phototransistor or photodarlington output • High speed 5 Mbit/sec (NRZ) OPI155 only • Hermetically sealed LED and photosensor • Base contact lead for conventional transistor biasing
Description: Each OPI150 and OPI153 is an optically coupled isolator that contains an infrared emitting diode and a NPN silicon phototransistor (OPI150) or photodarlington (OPI153), each sealed in an individual hermetically sealed package. The diode and phototransistor or diode and photodarlington are then optically coupled by means of a light pipe and mounted in a high dielectric plastic housing.
