Plastic Infrared Emitting Diode
OP266AA SERIES
Features:
• T-1 (3 mm) package style
• Narrow irradiance paꢂern
• 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 emiꢀng diode (GaAIAs) that is
molded in an IR transmissive clear or amber-ꢁnted epoxy package with a dome lens. Devices feature a narrow source
irradiance paꢂern and a variety of electrical characterisꢁcs. The small T-1 package style makes these devices ideal for space
-limited applicaꢁons.
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 ApplicaƟon BulleƟns 208 and 210 for addiƟonal design informaƟon and reliability (degradaƟon) data.

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 plasꢁcs.
