gaas infrared emitting diode se3450/5450 description 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 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. infra-83.tif outline dimensions in inches (mm) 3 plc decimals 0.005(0.12) tolerance 2 plc decimals 0.020(0.51) 2. anode 1. cathode (tab) leads: .046(1.17) .036(.91) 2 1 dia.
