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.
