Photodiode with sensitivity close to spectral luminous eﬃciency 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 Spectral response range: 480 to 660 nm Peak sensitivity wavelength: 550 nm Illuminometer Luminance meter Ceramic package for reliability Active area: 2.4 × 2.8 mm High-speed response: 0.5 μs (VR=0 V, RL=1 kΩ) Absolute maximum ratings (Ta=25 °C) Parameter Reverse voltage Operating temperature Storage temperature Symbol Condition VR Max. Topr No dew condensation*1 Tstg No dew condensation*1 *1: When there is a temperature diﬀerence between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface. Dew condensation on the product may cause deterioration in characteristics and reliability. 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.
