SLD-68HFBG1
Internal Infrared Rejection Filter
Planar Photodiode
Features
Fast switching time, Low capacitance
High responsivity
Linear response vs irradiance
IR Blocking Filter
Hermetic TO-46 case 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 irradiance
(Ee). Low dark current and low capacitance make it
the ideal detector for fast rise time applications.
Internal blue-green filter blocks infrared radiation.
