OP266AA SERIES
Features:
T-1 (3 mm) package style
Narrow irradiance pattern
Dome lens
Higher power output than GaAs at equivalent drive currents
850 nm diode
Description:
Each device in the OP266AA series is a high intensity gallium aluminum arsenide infrared emitting diode (GaAIAs) that is
molded in an IR transmissive clear or amber-tinted epoxy package with a dome lens. Devices feature a narrow source
irradiance pattern and a variety of electrical characteristics. The small T-1 package style makes these devices ideal for space
-limited applications.
These devices are mechanically and spectrally matched to other OPTEK products as follows:
The OP266AA family conform to the OP506 and OP535 series devices.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
Applications:
Space-limited applications
Applications requiring coupling efficiency
Battery-operated or voltage-limited
RoHS

To avoid stress cracking, we suggest using
ND Industries’ Vibra-Tite for thread-locking.
Vibra-Tite evaporates fast without causing structural failure in
OPTEK'S molded plastics.
