Infrared Rejection Filter
Planar Photodiode
Features
Low capacitance, fast switching time
Linear response vs irradiance
IR blocking filter
Multiple dark current ranges available
Description
The planar photodiode is designed to operate in
either photoconductive or photovoltaic modes. This
diode incorporates a BG filter that rejects infrared
wavelengths and approximates the response of the
human eye. High sensitivity and low dark current
allow use in low irradiance applications. The
photodiode measures 3.6 mm X 3.6 mm (0.140" X
0.140") and is supplied on a ceramic base with a
clear epoxy dome package.
