Description
The 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.
