50 kV electrical isolation
High speed >5MBd
Hermetically sealed LED and
photosensor
De scrip tion
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.
