Hi-Rel Optically Coupled Isolator
Types OPI120TX, OPI120TXV
Features
• High current transfer ratio
• 15 kV electrical isolation
• Base lead provided for conventional
transistor biasing
• Components processed to Optek’s
screening program patterned after
MIL-PRF-19500 for TX and TXV
devices
Description
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.
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.

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 25^o C.
(3) Derate linearly 2.5 mW/^o C above 25^o C.
(4) Methanol or isopropanol are recommended as cleaning agents.
