BPX43 Datasheet | Vishay

Vishay Telefunken Silicon NPN Phototransistor Description BPX43 is a very high sensitive silicon NPN epitaxial planar phototransistor in a standard TO- 18 hermetically 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.
