BPX43
Vishay Telefunken
Silicon NPN Phototransistor
Description
BPX43 is a very high sensitive silicon NPN epitaxial
planar phototransistor in a standard TO鈥?8 hermeti-
cally sealed metal case with a glass lens.
A superior linearity of photocurrent vs. irradiation
makes it ideal for linear applications. A base terminal
is available to enable biasing and sensitivity control.
