Description
TSUS540. series are infrared emitting diodes in standard GaAs on GaAs technology, molded in a clear, blue–grey tinted plastic package. The devices are spectrally matched to silicon photodiodes and phototransistors.

Features
● Low cost emitter
● Low forward voltage
● High radiant power and radiant intensity
● Suitable for DC and high pulse current operation
● Standard T–1 (ø 5 mm) package
● Comfortable angle of half intensity ϕ = ± 22°
● Peak wavelength λp = 950 nm
● High reliability
● Good spectral matching to Si photodetectors

Applications
    Infrared remote control and free air transmission systems with low forward voltage and comfortable radiation angle requirements in combination with PIN photodiodes or phototransistors.
