LED22FC-SMD5 TECHNICAL DATA Mid-Infrared LED, Flip-Chip Design, SMD Light Emitting Diodes with central wavelength 2.23 µm series are based on heterostructures grown on GaSb substrates. Solid solutions GaInAsSb are used in active layer. Wide band gap solid solutions AlGaAsSb with Al content 64% are used for good electron confinement. LED22FC-SMD5 has a stable ouput power and a lifetime more then 80000 hours.
