description

The CLD340 is a high temperature

AlGaAs photodiode designed for

sensitivity from 830 to 910nm. This

specialty detector eliminates the

need for signal modulation or

filtering of ambient light when used

where background illumination

could cause problems. The 0.040"

by 0.040" chip is mounted in a flat

window TO-46 package. The

CLE335 is recommended for

optical coupling.
