TEPT5600 Vishay, 40 ° IR + Visible Light Phototransistor, Through Hole 2-Pin 5mm (T-1 3/4) package

The TEPT series, from Vishay Semiconductor, are a family of ambient light sensors. They are available in either 3mm (T-1) or 5mm (T-1 3/4) through-hole packages. These NPN epitaxial planar phototransistors have a clear plastic package and are sensitive to visible light, similar to the human eye.
Suitable applications for the TEPT series include ambient light sensors or replacement CdS photoresistors.
