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.

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow
soldering.
(2) Derate lin early mW/°C above 25°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.
