Photo IC diodes
S7183
S7184
Linear current amplification of photodiode
output
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.

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
reliability.
