Vishay Telefunken BPW41N Datasheet
Silicon PIN Photodiode
Description
BPW41N is a high speed and high sensitive PIN photodiode in a flat side view plastic package.
The epoxy package itself is an IR filter, spectrally
matched to GaAs or GaAs on GaAlAs IR emitters
(l
= 950 nm).
p
The large active area combined with a flat case gives
a high sensitivity at a wide viewing angle.
