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.

This LED is built with a GaAlAs chip. Max allowable epoxy miniscus is 0.030". For identification purposes, Cathode lead is .065" .035" longer than the anode lead. Dimensions are in inches 2 Pin # LED 1 Cathode 2 Anode CONTAINS POLYSULFONE 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.

Derate linearly at 1.33 mW/ C above 25 C. 3. EE(APT) is a measurement of the average apertured radiant incidence upon a sensing area 0.081" (2.06 mm) in diameter, perpendicular to and centered on the mechanical axis of the lens and 0.590" (14.99 mm) from the measurement surface. EE(APT) is not necessarily uniform within the measured area.
