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.
notes:
1. 0.06” (1.5mm) from the header for 5 seconds maximum.
2. Derate linearly 1.0mW/°C from 25°C free air temperature to T_A = +225°C.
