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. These devices are designed for applications that require very high isolation between input and output.

FEATUREs:
• 50 kV electrical isolation
• Choice of phototransistor or photodarlington output
• High speed >5 MBd (OPI155)
• Hermetically sealed LED and photosensor
• Base contact lead for conventional transistor biasing
• TX and TXV process available (see Hi-Rel section)

APPLICATIONs:
• Requiring high voltage isolation between input and output
• Electrical isolation in dirty environments
• Industrial equipment
• Medical equipment
• Office equipment
