Silicon NPN Phototransistor
Description
BPW78 is a high sensitive silicon NPN epitaxial planar
phototransistor in a flat side view plastic package.
A small recessed lens provides a high sensitivity in a
low profile case.
The epoxy package itself is an IR filter, spectrally
matched to GaAs or GaAs on GaAlAs IR emitters
(C0108
p
> 850nm).
