The OP245PS is an 850 nm, infrared
emItting diode molded in IR transmissive
amber-tinted epoxy packages. The
side-looking package is for use in PC
board mounted slotted switches or as
easily mounted interrupt detectors.
The stable V
F
vs. Temperature
characteristic make them ideal for
applications where voltage is limited
(such as battery operation).
The low t

f
make them ideal for high
speed operations.
