Si photodiode



Photodiode with sensitivity close to spectral luminous efficiency

The S7686 is a Si photodiode having a spectral response characteristic that is more similar to the human eye sensitivity (spectral luminous efficiency) than our conventional visible-compensated sensors (S1133, etc.).

-Spectral response analogous to CIE spectral luminous efficiency
-Ceramic package for reliability
-Photosensitive area: 2.4 × 2.8 mm
-High-speed response: 0.5 us (VR=0 V, RL=1 kΩ)
-fs value: 8% typ. (vertical light input)
