GaAs/GaAlAs IR Emitting Diode in ø 5 mm (T–1¾)
Package
Description
TSAL6400 is a high efficiency infrared emitting diode
in GaAlAs on GaAs technology , molded in clear , bluegrey tinted plastic packages.
In comparison with the standard GaAs on GaAs
technology these emitters achieve more than 100 %
radiant power improvement at a similar wavelength.
The forward voltages at low current and at high pulse
current roughly correspond to the low values of the
standard technology. Therefore these emitters are
ideally suitable as high performance replacements of
standard emitters.
