Product Summary

The BPX43 is a very high sensitive silicon NPN epitaxial planar phototransistor. The BPX43 is 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 of the BPX43 is available to enable biasing and sensitivity control. The applications of the BPX43 include Detector for analogue and digital applications in industrial electronics, measuring and control, e.g. long range light barriers with additional optics, optical switches, alarm systems.
