Photo IC diode
S9648-200SB
Plastic package shaped the same as metal package
The S9648-200SB photo IC has spectral response close to human eye sensitivity. Two photosensitive areas are made on a
single chip. Almost only the visible range can be measured by finding the difference between the two output signals in the in-
ternal current amplifier circuit. Compared to the previous type, the S9648-200SB offers lower output fluctuations for light sources
producing the same illuminance at different color temperatures. The S9648-200SB is encapsulated in a plastic package having
the same shape as a metal package. The shape of the S9648-100 also resembles our 5R type visible sensors (CdS photoconduc-
tive cells), so the S9648-200SB can be used as a replacement for those visible sensors.
Features
Spectral response close to human eye sensitivity
is attained without using visual-compensated filter.
Operation just as easy to use as a photodiode
Lower output-current fluctuations compared with
phototransistors and CdS photoconductive cells.
Excellent linearity
Low output fluctuations for light sources producing the
same illuminance at different color temperatures
Applications
Energy-saving sensor for TVs, etc.
Light dimmers for liquid crystal panels
Various types of light level measurement

*1: Power dissipation decreases at a rate of 3.3 mW/°C above Ta=25 °C.
*2: 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 absolute maximum ratings.
