Plastic Infrared Emitting Diode OP266FAA 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 OP266FAA series is a high intensity gallium 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: OP266 devices 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 applications DIMENSIONS ARE IN: Ordering Information Part Number LED Peak Wavelength OP266FAB IF (mA) Typ / Max Total Beam Angle Lead Length 20 / 50 18° 0.50” 5.5 / NA OP266FAA [MILLIMETERS] INCHES Output Power (mW/ cm2) Min / Max 850 nm 7.5 / 12.5 OP266FAC 11.5 / 16.5 OP266FAD 15.5 / NA NOTES: 1. 2. 3. 4. 1 Outside discrete shell is polysulfone CLEAR. This LED is built with a 0.011 X 0.011 GaAlAs chip. Max allowable epoxy miniscus is 0.030”. For identification purposes, Cathode lead is .065” ± .035” longer than the anode lead. DISCRETE PIN OUT 1 2 CATHODE ANODE 2 Pin # LED 1 2 Cathode 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.

RMA flux is recommended. Duration can be extended to 10 second maximum when flow soldering. A maximum of 20 grams force may be applied to the leads when soldering. 2. 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.
