DESCRIPTION

BPW21R is a planar Silicon PN photodiode in a hermetically

sealed short TO-5 case, especially designed for high

precision linear applications.

Due to its extremely high dark resistance, the short circuit

photocurrent is linear over seven decades of illumination

level.

On the other hand, there is a strictly logarithmic correlation

between open circuit voltage and illumination over the same

range.

The device is equipped with a flat glass window with built in

color correction filter, giving an approximation to the

spectral response of the human eye.
