Visible Radiant Optical Sensor /Data Sheet BCS2015G1 BCS2015G1 is the photodiode which uses an amorphous silicone Application semiconductor on the glass substrate. 　It is the most suitable for • Brightness control for LCD, EL and CRT Brightness Adjustment, Control of the Lighting systems. BCS2015G1 is • Brightness control for Keypads (e. g. Mobile Phones) for surface mounthing. • Positioning scanline for Rear Projecton TV • Exposure adjust for Compact Camera Features • Sub exposure adjust for Digital Camera • Highly receptive to visible light but not receptive to infrared light (close to Human eye visibility). • Accurate illumination measurement can be taken without the use of an infrared filter. ( Phototransistors and photodiodes that use crystal- silicon semiconductors typically require this filtering.) • Surface mounting can be used in lead- free reflow soldering. • Lead- free, Cadmium-free Shapes and dimension Glass Substrate BCS2015G1 Photo acceptance area 0.6 (1.25) 0.6 0.5 0.6 Dimensions in [mm] Tolerance:±0.2mm ( ) : Typical value t=0.6 typ.
