Vishay Semiconductors
High Speed Infrared Emitting Diode, 870 nm, GaAlAs Double
Hetero
Description
The TSHA520. 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
70 % radiant power improvement.
Features
• Extra high radiant power and radiant intensity
• Suitable for high pulse current operation
• Standard T-1¾ (∅ 5 mm) package
• Angle of half intensity ϕ = ± 12 °
• 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 and long transmission distance
requirements 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.
