| High Speed GaAlAs Infrared Emitter OPE5685 The OPE5685 is GaAlAs infrared emitting diode that is designed for high power, low forward voltage and high speed rise / fall time. This device is optimized for speed and efficiency at emission wavelength 850nm and has a high radiant efficiency over a wide range of forward current. This device is packaged T1-3/4 plastic package and has wide beam angle with lensed package and cup frame. Especially this device is suited as the emitter of data transmission without cable. FEATURES * High speed : 25ns rise time * 850nm wavelength * Wide beam angle * Low forward voltage * High power and high reliability * Available for pulse operating APPLICATIONS * Emitter of IrDA * IR Audio and Telephone * High speed IR communication * IR LANs * Available for wireless digital data transmission DIMENSIONS (Unit : mm) 5.0 1.3 Max 5.7 8.7 24.0 Min 7.7 2- 0.5 2.0 2.5 Anode Cathode Tolerance : 0.2mm STORAGE * Condition : 5C~35C,R.H.60% * Terms : within 3 months from production date * Remark : Once the package is opened, the products should be used within a day. Otherwise, it should be keeping in a damp proof box with desiccants. * Please take proper steps in order to secure reliability and safety in required conditions and environments for this device.
