(OPB710F, OPB730F)
F-Package
Description:
OPB710
and
OPB710F
consist of a gallium arsenide infrared emitting diode and an NPN silicon
phototransistor.
OPB730
and
OPB730F
consist of a gallium arsenide infrared emitting diode and an
NPN silicon photodarlington.
On each sensor, the emitting diode and detector are mounted side-by-side on parallel axes in a
standard TO-72 header. A black plastic sleeve is attached and filled with encapsulating epoxy to cover
the emitter and detector.
The
OPB710F
and
OPB730F
(“F” versions) have a filtering material added to the epoxy to reduce the
effect of ambient light. The package contains an internal barrier which prevents diode emissions from
reaching the sensor directly.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
Derate linearly 1.67 mW/°C above 25 ° C.
Derate linearly 3.33 mW/°C above 25 ° C.
Measured using Eastman Kodak neutral white test card having 90% diffuse reflectance located .250 inch (6.35 mm) from the
face of the OPB710/OPB730. Reference: Eastman Kodak, Catalog #E 152 7795.
Crosstalk (ICX) is the collector current measured with the indicated current on the input diode and with no reflecting surface.
Ambient light is excluded with a black box.
