SE3450/5450 GaAs Infrared Emitting Diode FEATURES • TO-46 metal can package • Choice of flat window or lensed package • 90¡ or 20¡ (nominal) beam angle option • 935 nm wavelength • Wide operating temperature range (- 55¡C to +125¡C) • Mechanically and spectrally matched to SD3421/5421 photodiode, SD3443/5443/5491phototransistor, SD3410/5410 photodarlington and SD5600 series Schmitt trigger INFRA-83.TIF DESCRIPTION The SE3450/5450 series consists of a gallium arsenide infrared emitting diode mounted in a TO-46 metal can package. The SE3450 series has flat window cans providing a wide beam angle, while the SE5450 series has glass lensed cans providing a narrow beam angle. The TO-46 packages offer high power dissipation capability and are ideally suited for operation in hostile environment.
