De scrip tion

The OP268FPS contains an 850 nm
gallium aluminum arsenide infrared
emitting diode molded in an
“end-looking” miniature black package.
This device has a wide radiation angle
due to its flat emitting surface. The point
source GaAIAs IRED emits photons from
a 0.004” diameter area centered with the
optical centerline. Small size and 0.100”
(2.54 mm) lead spacing allow
considerable design flexibility.

The stable VF vs. Temperature
characteristic make them ideal for
applications where voltage is limited
(such as battery operation).
