Plastic package photodiode with low dark current The 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. S1787-04: For visible range S1787-08: For visible to IR range S1787-12: For visible to near IR range Exposure meter Illuminometer Camera auto exposure Stroboscope light control Copier Display light control Optical switch, etc. Structure / Absolute maximum ratings Window material* Effective active area Active area size Absolute maximum ratings Reverse voltage Operating temperature Storage temperature VR max Topr Tstg (V) (°C) (°C) 10 * Window material R: resin coating, V: visual-compensation filter, I: infrared-cutting filter Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings. Electrical and optical characteristics (Typ.
