PRODUCT DESCRIPTION
The PD500 is an InGaAs photodiode with a
photosensitive region 500
m in diameter. It is
intended for use in high sensitivity
instrumentation, laser back-facet monitoring
and low bit rate communication systems.
Planar semiconductor design and dielectric
passivation provide superior noise performance.
The device can be assembled on a ceramic sub-
mount or in an hermetic TO46 can. Custom
packages are an option.
