Photo IC diode
Reduced color temperature errors

The S11154-201CT is a photo IC diode with spectral response characteristics that closely resemble human eye sensitivity. Two active areas are formed on the same chip, and the outputs of the two active areas are subtracted from each other by the current amplifier circuit, in order to have sensitivity almost only in the visible range and reduce the color temperature errors.

FEATUREs
➤ Spectral response close to human eye sensitivity
➤ Reduced color temperature error
➤ Lower output-current variation compared with phototransistors
➤ Excellent linearity
➤ Low output deviation by different color temperature light source
➤ Suitable for lead-free reflow (RoHS compliance)

APPLICATIONs
➤ Energy-saving sensor for large-screen TVs, etc.
➤ Various types of light level measurement
