Photodiode Array
Features
4 planar photodiode elements
Wide acceptance angle
Low capacitance, fast switching time
Low leakage current
Linear response vs irradiance
8 pin Dual In-line package
Description
This Silonex photodiode array consists of four
passivated silicon elements that are individually
connected to terminals on the edge of the package.
This photodetector is designed to operate in either
photovoltaic or reverse bias mode. It has excellent
linearity in response versus light intensity. Low dark
current and low capacitance makes it the ideal
detector for fast rise time applications.
An epoxy
dome protects the array elements from mechanical
damage while providing a wide angle of view.
