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.

Notes:
(1) RMA flux is rec om mended. Du ra tion can be ex tended to 10 seconds maximum when flow
sol der ing.
(2) De rate lin early mW/°C above 25° C.
(3) Mea sured with in put and out put leads shorted and rel a tive hu mid ity of less than 50%.
This de vice is sus cep ti ble to dam age from elec tro static dis charge (ESD). Nor mal static
pre cau tions should be taken in the han dling of this de vice to pre vent ESD dam age.
