SLED-56E1
GaAs Infrared Emitting Diode
Features
High output at low current
Very wide emission angle
Multiple power ranges
TO-46 base package
Description
This Silonex device is a high output Gallium Arsenide
infrared emitting diode which produces a peak
radiation at 940 nm when forward biased.
It is
packaged in a low profile clear epoxy dome for wide
angle radiation emission.
