Output Photosensor
The OPI120TX and OPI120TXV are
optically coupled isolators, each
consisting of a gallium aluminum
arsenide infrared light emitting diode
(OP235TX or OP235TXV) and an NPN
silicon phototransistor (OP804TX or
OP804TXV) sealed in a high dielectric
plastic housing. This series is designed
for applications requiring high voltage
isolation between input and output.

Notes:
(1) Measured with input leads shorted together and output leads shorted together in air with a
maximum relative humidity of 50%. If suitably encapsulated or oil immersed, the isolation
voltage is increased to at least 25 kV.
(2) Derate linearly 2.0 mW/o C above 25o C.
(3) Derate linearly 2.5 mW/o C above 25o C.
(4) Methanol or isopropanol are recommended as cleaning agents.
High reliability processing is performed at
the component level in accordance with
MIL-PRF-19500 for both the infrared light
emitting diode and the NPN silicon
phototransistor.Typical screening and lot
acceptance tests are provided on page
13-4.

in measurement results.
