GaAs/GaAlAs IR Emitting Diode in ø 3 mm (T–1)
Package
Description
94 8488
TSAL4400 is a high efficiency infrared emitting diode
in GaAlAs on GaAs technology, molded in clear, blue-
grey tinted plastic packages.
In comparison with the standard GaAs on GaAs
technology these emitters achieve about 100 % ra-
diant 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.
Features
D Extra high radiant power
D Low forward voltage
D Suitable for high pulse current operation
D Standard T–1 (ø 3 mm) package
D Angle of half intensity ϕ = ± 25°
D Peak wavelength lp = 940 nm
D High reliability
D Good spectral matching to Si photodetectors
Applications
Infrared remote control units
Free air transmission systems
Infrared source for optical counters and card readers
