TSUS520.
Vishay Semiconductors
Infrared Emitting Diode, 950 nm, GaAs
Description
TSUS520. series are infrared emitting diodes in stan-
dard GaAs on GaAs technology, molded in a clear,
blue-grey tinted plastic package. The devices are
spectrally matched to silicon photodiodes and pho-
totransistors.
