GaAlAs Infrared Emitting Diodes in ø 5 mm (T–1

¾)

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.

Features

D Extra high radiant power and radiant intensity

D Suitable for high pulse current operation

D Standard T–1¾ (ø 5 mm) package

D Angle of half intensity ϕ = ± 12°

D High reliability

D Good spectral matching to Si photodetectors

94 8390

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.
