Photo IC diodes
Linear current amplification of photodiode
The S7183 and S7184 consist of a photodiode and a signal processing circuit for amplifying the photocurrent generated
from the photodiode up to 1300 times. Despite a small active area, these photo ICs provide an output nearly equal to that
from photodiodes with a 20 × 20 mm active area. Both S7183 and S7184 can be used the same way as a reverse-biased
photodiode, and in most cases, they deliver a sufﬁcient output voltage by just connecting a load resistor.
Clear plastic package
Operation just as easy as using photodiodes
Large output current rivaling that of a phototransistor
Energy saving sensors for TV brightness controls, etc.
Light dimmers for liquid crystal panels
Various types of light level measurement
Absolute maximum ratings (Ta=25 °C)
-0.5 to +16
Topr No dew condensation*2
-30 to +80
Tstg No dew condensation*2
-40 to +85
260 °C, 3 s, at least 2.5 mm away from package surface
350 °C, 3 s
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.
*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
