Datasheet
Phototransistor, top view type
RPT-37PB3 F
The RPT-37PB3F is a silicon planar phototransistor. Since it is m o lded in plast ic with a visible light filter,
there is almost no eff ect from st ray light. It is particularly suited for use with a ROHM SIR-34ST 3F
infr ar ed light emitt ing diode. It is possible t o distinguish the polarit y by the shape of ramp type.
Applications Outline
• Optical contr o l equipment
• Receiver for sensors
Features
1) High sensitivity.
2) Almost no effect from st r ay lig ht .

measures such as complying with the derating characteristics, implementing redundant and
fire prevention designs, and utilizing backups and fail-safe procedures. ROHM shall have no
responsibility for any damages arising out of the use of our Poducts beyond the rating specified by
ROHM.
Examples of application circuits, circuit constants and any other information contained herein are
provided only to illustrate the standard usage and operations of the Products. The peripheral
conditions must be taken into account when designing circuits for mass production.
The technical information specified herein is intended only to show the typical functions of and
examples of application circuits for the Products. ROHM does not grant you, explicitly or implicitly,
