OP265, OP266 Series (A, B, D, W) Features:  T-1 (3 mm) package style  Choice of narrow or wide irradiance pattern  Choice of dome or flat lens  Mechanically and spectrally matched to other OPTEK devices  Higher power output than GaAs at equivalent drive currents  890 nm diodes Description: Each device in the OP265 and OP266 series is a high intensity gallium arsenide infrared emitting diode (GaAIAs) that is molded in an IR transmissive clear epoxy package with either a dome or flat lens. Devices feature narrow and wide irradiance patterns and a variety of electrical characteristics. The small T-1 package style makes these devices ideal for space-limited applications. OP265 devices conform to the OP505 and OP535 series devices. OP266 devices conform to OP506 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 Ordering Information Part LED Peak Output Power (mW/cm2) I (mA) Total Beam Lead F Number Wavelength Min / Max Typ / Max Angle Length OP265A 2.70 / NA OP265B 1.65 / 4.70 18° OP265D 0.54 / NA OP265W 1.00 / NA 90° See page 890 nm 20 / 50 2 OP266A 2.70 / NA OP266B 1.65 / 4.70 18° OP266D 0.54 / NA OP266W 1.00 / NA 90° RoHS General Note OPTEK Technology, Inc.
