Silicon NPN Phototransistor
Description
BPW85 is a high speed and high sensitive silicon NPN
epitaxial planar phototransistor in a standard T–1 (ø 3
mm) plastic package. Due to its waterclear epoxy the
device is sensitive to visible and near infrared radiation.
The viewing angle of ± 25° makes it insensible to ambient straylight.
