Planar Photodiode
Features
Planar photodiode
Low capacitance
Fast switching time
Low leakage current
Linear response vs irradiance
TO-46 base with epoxy dome lens
Multiple dark current ranges available
Description
This planar, passivated silicon photodetector is
designed to operate in either photovoltaic or reverse
bias mode to provide low capacitance with fast
switching speed. It provides excellent linearity in
output signal versus light intensity. Low dark current
and low capacitance make it the ideal detector for fast
rise time applications.
