DESCRIPTION
The SE1470 is a high intensity aluminum gallium
arsenide infrared emitting diode mounted in a glass
lensed metal can coaxial package. The package may
have a tab or second lead welded to the can as an
optional feature (SE1470-XXXL). Both leads are flexible
and may be formed as required to fit various mounting
configurations. These devices typically exhibit 70%
greater power intensity than gallium arsenide devices at
the same forward current.
