Description
TSAL4400 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 about 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.
Features
● Extra high radiant power
● Low forward voltage
● Suitable for high pulse current operation
● Standard T–1 (ø 3 mm) package
● Angle of half intensity ϕ = ± 25
● Peak wavelength p = 940 nm
● High reliability
● Good spectral matching to Si photodetectors
Applications
Infrared remote control units
Free air transmission systems
Infrared source for optical counters and card readers
