Subminiature package phototransistor The S2829 is a high sensitivity phototransistor molded into a visible-cut plastic package. Subminiature plastic package with lens Rotary encoders Visible-cut package Touch screen Absolute maximum ratings (Ta=25 °C) Parameter Collector-emitter voltage Emitter-collector voltage Collector current Collector dissipation Operating temperature Storage temperature Soldering Symbol VCEO VECO Ic Pc Topr Tstg - Value 35 4 20 80 -25 to +85 -40 to +100 260 °C, 3 s, at least 2.5 mm away from package surface *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.
