The SFH 309 FA-5/6 part of OSRAM is an infrared diode that operates in the visible wavelength range from 805 nm. This diode is used for infrared data transmission, optical detection, and distance measurement. The SFH 309 is a leaded device that consists of an eye-safe infrared (IR) led chip mounted in an epoxy housing. It has an operational wavelength of 805 nm, a maximum forward voltage of 1.65V, and a maximum forward current of 18mA. The clear epoxy window provides a good field of view. This diode is RoHS compliant and is suitable for a variety of applications, including surface-mount design and infrared illumination.
