Product Bulletin OP231 June 1996 (GD.OPTEK GaAlAs Hermetic Infrared Emitting Diodes Types OP231, OP232, OP233 Features e Enhanced temperature range e TO-46 hermetically sealed package Mechanically and spectrally matched to OP800, OP593, and OP598 phototransistors * Specified apertured power in ranges to satisfy most applications e Variety of power ranges Description The OP231 series devices are gallium aluminum arsenide infrared emitting diodes mounted in hermetic TO-46 housings. Gallium aluminum arsenide features higher radiated output than gallium arsenide at the same forward current. The wavelength is centered at 890 nm which closely matches the spectral response of silicon phototransistors. The OP231 series is lensed to provide a narrow beam angle (18 between half power points). The narrow beam angle and the specified radiant intensity of the OP231 series allow ease of design in beam interrupt applications in conjunction with the OP800 or OP598 series photosensor. Please refer to application bulletins 208 and 210 for additional design information and reliability (degradation) data. Optek Technology, Inc.

(3) EeiaPT) is a measurement of the average radiant intensity within the cone formed by the measurement surface, a radius of 1.429" (36.30 mm) measured from the lens side of the tab to the sensing surface and a sensing surface of 0.250" (6.35 mm) in diameter forming a 10 cone. Eaapty is not necessarily uniform within the measured area. (4) Measurement made with 100s pulse measured at the trailing edge of the pulse with a duty cycle of 0.10% and an ir = 100 mA.
