SE3455/5455 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 (- 55C to +125C) * Ideal for high pulsed current applications * Mechanically and spectrally matched to SD3421/5421 photodiode, SD3443/5443/5491phototransistor, SD3410/5410 photodarlington and SD5600 series Schmitt trigger INFRA-83.TIF DESCRIPTION The SE3455/5455 series consists of a gallium arsenide infrared emitting diode mounted in a TO-46 metal can package. The SE3455 series has flat window cans providing a wide beam angle, while the SE5455 series has glass lensed cans providing a narrow beam angle. These devices are constructed with dual bond wires suitable for pulsed current applications. The TO-46 packages offer high power dissipation capability and are ideally suited for operation in hostile environments.
