Sensors Phototransistor, top view type RPT-38PB3F The RPT-38PB3F is a silicon planar phototransistor. Since it is molded in plastic with a visible light filter, there is almost no effect from stray light. It is particularly suited for use with a ROHM SIR-34ST3F infrared light emitting diode. Applications Optical control equipment Features 1) High sensitivity. 2) Almost no effect from stray light. 3) Low cost plastic package.
