Description:
Each
OP245PS
device is an infrared emitting diode with a 850 nm GaAIAs chip, molded in a clear IR-transmissive
side-looking epoxy package. This package makes these devices ideal for PCBoard mounted slotted switches and
for mounted interrupt detectors.
The stable forward V
F
vs T
A
characteristic make them suitable for applications that have limited voltage, such as
battery operation; whereas, the low T
R
/T
F
makes them ideal for high-speed operations.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.

To avoid stress cracking, we suggest using
ND Industries’
Vibra-Tite
for thread-locking.
