App note: Understanding infrared diode power ratings

an_ttelectronics_ir_specs

App note from TT Electronics about infrared diode specs, how they vary from different manufacturers, and help clear things about infrared definition of parameters. Link here (PDF)

Infrared emitting diode power measurement is dependent upon a number of variables which must be precisely defined in order for design engineers to utilize data sheet information. Manufacturers differ not only in the techniques used in measuring power, but also in their interpretations of the definitions of the parameters which are measured. This application bulletin is intended to clarify this misunderstanding, especially for GaAs and GaAlAs solution grown epitaxial devices.
