AlGaAs Infrared Emitting Diode
SE3470/5470
DESCRIPTION
FEATURES
TO-46 metal can package
•
Choice of flat window or lensed package
•
90¡ or 20¡ (nominal) beam angle option
•
880 nm wavelength
•
Higher output power than GaAs at equivalent
drive currents
•
Wide operating temperature range
(-55¡C to +125¡C)
•
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
•
The SE3470/5470 series consists of aluminum gallium
arsenide infrared emitting diode mounted in a TO-46
metal can package. The SE3470 series has flat window
cans providing a wide beam angle, while the SE5470
series has glass lensed cans providing a narrow beam
angle. These devices typically exhibit 70% greater
power output than gallium arsenide devices at the same
forward current. The TO-46 packages offer high power
dissipation capability and are ideally suited for operation
in hostile environments.
