DESCRIPTION
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.
