Infrared light emitting diode, top view type
SIR-341ST3F
The SIR-341ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous
efficiency and a 940nm peak wavelength suitable for silicon detectors. It is small and at the same time has a wide
radiation angle, marking it ideal for compact optical control equipment.
!Applications
Optical control equipment
Light source for remote control devices
!Features
1) Compact (φ3.1mm).
2) High efficiency, high output PO=8.4mW (IF=50mA).
3) Wide radiation angle θ 1/216deg.
4) Peak wavelength well suited to silicon detectors
(λP=940nm).
