IR Emitter and Detector
LTE-S9711-J
1. Description
Lite-On offers a broad range of discrete infrared components for application such as remote control, IR wireless data
transmission, security alarm & etc. Customers need infrared solutions featuring high power, high speed and wide viewing
angels. The product line includes GaAs 940nm IREDs, AlGaAs high speed 850nm IREDs, PIN Photodiodes and
Phototransistors. Photodiodes and Phototransistors can be provided with a filter that reduces digital light noise in the sensor
function, which enables a high signal-to-noise ratio.

NOTE:
1.
θ1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength,
λd
is derived from the CIE chromaticity diagram and represents the single wavelength which defines
the color of the device.
3. Reverse voltage (V

8. CAUTIONS
8.1. Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office equipment, communication
equipment and household applications).Consult Liteon’s Sales in advance for information on applications in which exceptional
reliability is required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in
aviation, transportation, traffic control equipment, medical and life support systems and safety devices).
8.2. Storage
The package is sealed:
The LEDs should be stored at 30°C or less and 90%RH or less. And the LEDs are limited to use within
one year, while the LEDs is packed in moisture-proof package with the desiccants inside.
The package is opened:
The storage ambient for the LEDs should not exceed 30° temperature or 60% relative humidity.
C
It is recommended that LEDs out of their original packaging are IR-reflowed within one week hrs.
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a sealed container with
appropriate desiccant, or in a desiccators with nitrogen ambient.
LEDs stored out of their original packaging for more than one week hrs should be baked at about 60 deg C for at least 20
hours before solder assembly.
8.3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.
