High Speed Infrared Emitting Diode, 870 nm, GaAlAs Double
Hetero
Description
The TSHA44..series are high efficiency infrared emitting diodes in GaAlAs on GaAlAs technology, molded
in a clear, untinted plastic package.
In comparison with the standard GaAs on GaAs technology these high intensity emitters feature about
50 % radiant power improvement.
Features
• Extra high radiant power
• High radiant intensity for long transmission distance
• Suitable for high pulse current operation
• Standard T-1(∅ 3 mm) package for low space
application
• Angle of half intensity ϕ = ± 20°
• Peak wavelength λ
= 875 nm
p
• High reliability
• Good spectral matching to Si photodetectors
• Lead-free component
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
Applications
Infrared remote control and free air transmission systems with high power requirements in combination
with PIN photodiodes or phototransistors.
Because of the very low radiance absorption in glass
at the wavelength of 875 nm, this emitter series is also
suitable for systems with panes in the transmission
range between emitter and detector.
