LED23FC-SMD5
v 1.1 6.11.2013
Description
LED23FC-SMD5 is fabricated from narrow band-gap GaInAsSb/AlGaAsSb heterostructures lattice
matched to GaSb substrate. This surface mount Mid-IR LED provides a typical peak wavelength of
2.35 µm and optical power of typ. 1 mW qCW. It comes in low temperature co-fired ceramic SMD
package, with anode and cathode metalized areas on the back side of the surface.

Suitable Drivers and Evaluation Boards
We recommend to use Quasi Continuous Wave (qCW) mode with duty cycle 50% or 25% to obtain maximum
average optical power, and short Pulse mode to obtain maximum peak power.
CW (continuous wave) mode is NOT recommended!
