High Speed GaAlAs Infrared Emitter

OPE5685

The OPE5685 is GaAlAs infrared emitting diode

DIMENSIONS(Unit : mm)

that is designed for high power, low forward voltage

and high speed rise / fall time.

This device is optimized for speed and efficiency

at emission wavelength 850nm and has a high radiant

efficiency over a wide range of forward current.

This device is packaged T1-3/4 plastic package

and has wide beam angle with lensed package

and cup frame. Especially this device is suited

as the emitter of data transmission without cable.
