Silicon Photodiode, RoHS Compliant
DESCRIPTION
BPW20RF 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.
Equipped with a clear, flat glass window, the spectral
responsitivity reaches from blue to near infrared.
