BPW77N
Silicon NPN Phototransistor
Description
BPW77N is a very high sensitive silicon NPN epitaxial
planar phototransistor in a standard TO–18 hermetically
sealed metal case.
Its glass lens featuring a viewing angle of
±10
°
makes it
insensible to ambient straylight.
A base terminal is available to enable biasing and sensi-
tivity control.
