Notes: (1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. (2) Derate lin early mW/ above 25C. C (3) Measured with input and output leads shorted and rela tive humidity of less than 50%. This device is susceptible to damage from electrostatic discharge (ESD). Normal static precautions should be taken in the handling of this device to prevent ESD damage.
Description
The OPI155 contains a high speed monolithic photo-IC comprised of a photodiode and DC amplifier driving an open collector output Schottky transistor. It is optically coupled by means of an internal light pipe and mounted in a high dielectric plastic housing. The LED and sensor are in hermetically sealed packages. It is designed for applications requiring high speed and high voltage isolation between input and output.
