SLD-68HF1
Planar Photodiode
Features
Low capacitance, fast switching time
Low leakage current
Linear response vs irradiance
Hermetic package with flat window
Multiple dark current ranges available
Description
This small area planar, passivated silicon
photodetector is designed to operate in either
photovoltaic or reverse bias mode. It provides
excellent linearity in output signal versus light
intensity. Low dark current and low capacitance
makes it the ideal detector for fast rise time
applications.
