PHOTODIODE Si photodiode S1787 series Plastic package photodiode with low dark current S1787 series is a family of plastic package photodiodes that offer low dark current. Plastic package used is light-impervious, so no stray light can reach the active area from the side or backside. This allows reliable optical measurements in the visible to near infrared range, over a wide dynamic range from low light levels to high light levels. Features Applications l S1787-04: For visible range l Exposure meter l Illuminometer l Camera auto exposure l Stroboscope light control l Copier l Display light control l Optical switch, etc. S1787-08: For visible to IR range S1787-12: For visible to near IR range General ratings / Absolute maximum ratings Type No. Active area size Window material * Effective active area Absolute maximum ratings Operating Reverse Storage temperature voltage temperature Topr VR Max.
