Description:
Each Optically coupled isolator in this data sheet contains an infrared Light Emitting Diode (LED) and a NPN silicon Photosensor. The OPI210 and OPI211 devices have 890 nm Light Emitting Diode (LED) and NPN phototransistor and coupled on an FR-4 substrate. The devices are made with a sealed internal optically transmissive path between the LED and the photosensor.
The OPI210 and OPI211 are identical except for the DC current transfer ratio. Both were designed with high reliability in mind and are ideally suited for use in MIL-STD-883 applications. The devices may be mounted using either silver or gold filled epoxies. The top of the device is covered with a silicone material and is very sensitive to acetone type cleaning material.
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.

Features:
• 1kV electrical isolation
• Miniature package ideal for surface mount applications
• TTL, DTL compatible
• High DC Current Transfer ratio

Applications:
• Military equipment
• High-Reliability environments
• High voltage isolation between input and output
• Electrical isolation in dirty environments
• Medical equipment
• Office equipment
