Package
Description
The TSHA520. series are high efficiency infrared emit-
ting 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
70 % radiant power improvement.

Good spectral matching to Si photodetectors
Applications
Infrared remote control and free air transmission systems with high power and long transmission distance re-
quirements in combination with PIN photodiodes or phototransistors.
Because of the reduced 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.
