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
Optical control equipment
Receiver for sensors
!!!!Features
