| Visible Radiant Optical Sensor /Data Sheet BCS2015G1 is the photodiode which uses an amorphous silicone semiconductor on the glass substrate. It is the most suitable for Brightness Adjustment, Control of the Lighting systems. BCS2015G1 is for surface mounthing. Features * 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 Glass Substrate BCS2015G1 BCS2015G1 Application * Brightness control for LCD, EL and CRT * Brightness control for Keypads (e. g. Mobile Phones) * Positioning scanline for Rear Projecton TV * Exposure adjust for Compact Camera * Sub exposure adjust for Digital Camera Shapes and dimension Photo acceptance area 0.6 (1.25) Photo acceptance area 0.6 0.5 0.6 Dimensions in [mm] Tolerance:0.2mm ( ) : Typical value (1.2) 1.5 2 - Electrode ( ) + Electrode Marker of polarity Electrical Characterisic Output current Output current Dark current 100Lux*1 100Lux*1 VR=0.05V Item Item VR=0V (Short Circuit Current) VR=5V Temperature= 25deg.C 1 t=0.6 typ.
