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.
!!!!Application
Optical control equipment
Receiver for sensors
!!!!Features
1) High sensitivity.
2) Almost no effect from stray light.
!!!!Absolute maximum ratings (Ta = 25°C)
