Phototransistor, top view type Datasheet RPT-37PB3F The RPT-37PB3F 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. It is possible to distinguish the polarity by the shape of ramp type. Applications Outline * Optical control equipment * Receiver for sensors Features 1) High sensitivity. 2) Almost no effect from stray light.
