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.
