BPW20R
Vishay Telefunken
Silicon PN Photodiode
Description
BPW20R is a planar Silicon PN photodiode in a
hermetically sealed short TO鈥? case, especially de-
signed for high precision linear applications.
Due to its extremely high dark resistance, the short cir-
cuit photocurrent is linear over seven decades of
illumination level.
On the other hand, there is a strictly logarithmic
correlation between open circuit voltage and illumina-
tion over the same range.
Equipped with a clear, flat glass window, the spectral
responsitivity reaches from blue to near infrared.
