The SME6700 and SMD6400 Series surface mount infrared
components are small plastic packages (2,8 mm x 3,2 mm x 1,5 mm/
0.110 in x 0.126 in x 0.073 in) in an un-lensed, top emitting and sensing
package.
These surface mount infrared components are designed for high
density placement by automatic assembly machinery.
The SME6700 is an aluminum gallium arsenide infrared emitting diode
(IRED). This component supplies optimum optical characteristics and
can be used with the SMD6400 phototransistor. The small size and high
power dissipation properties of the IRED promote PC (Printed Circuit)
board miniaturization and high density placement.
These surface mount infrared components are available in bulk, or on
tape and reel for use with automatic placement equipment.
