DESCRIPTION
T1070P ambient light sensor chip is a silicon NPN epitaxial
planar phototransistor. It is sensitive to visible light much like
the human eye and has peak sensitivity at 570 nm.

GENERAL INFORMATION
The datasheet is based on Vishay optoelectronics sample testing under certain predetermined and assumed conditions, and is
provided for illustration purpose only. Customers are encouraged to perform testing in actual proposed packaged and used
conditions. Vishay optoelectronics die products are tested using Vishay optoelectronics based quality assurance procedures
and are manufactured using Vishay optoelectronics established processes. Estimates such as those described and set forth in
this datasheet for semiconductor die will vary depending on a number of packaging, handling, use, and other factors. Therefore
sold die may not perform on an equivalent basis to standard package products.
