TEMT6000 ambient light sensor analog light intensity module visible light sensor

Description

TEMT6000 is a silicon NPN epitaxial planar phototransistor

in a miniature transparent mold for surface

mounting onto a printed circuit board. The device

is sensitive to the visible spectrum.

Features

• Adapted to human eye responsivity

• Wide angle of half sensitivity ϕ = ± 60°

• SMD style package on PCB technology

• Suitable for IR reflow soldering

• Lead free component

• Component in accordance to RoHS 2002/95/EC
