PRODUCT DESCRIPTION
The PD3M is an InGaAs photodiode with a
photosensitive region 3mm in diameter.
Applications include sensing and other high
sensitivity instrumentation. Class A devices
feature very low dark current and high shunt
resistance.
High reliability is assured through planar
semiconductor design and dielectric passivation.
The device can be assembled on a ceramic sub-
mount or in an hermetic TO5 can. Custom
packages are an option.
