LED35-SMD3

TECHNICAL DATA

Mid-Infrared Light Emitting Diode, SMD

Light Emitting Diodes with central wavelength 3.55 µm series are based on heterostructures grown

on InAs substrates by MOCVD. InAsSb is used in the active layer. Wide band gap solid solutions

InAsSbP with P content 50% are used for god electron confinement.

LED50-SMD3 has a stable ouput power and a lifetime more then 80000 hours.

Features

• Structure: InAsSb/InAsSbP

• Peak Wavelength: typ. 3.55 µm

• Optical Ouput Power: typ. 30 µW qCW

• Package: SMD 3x3 mm
