|
 |
The RPT-34PB3F is a silicon planar phototransistor. It is particularly suited for use with a ROHM SIR-34ST3F infrared light emitting diode. The SIR-34ST3F is a GaAs infrared light emitting diode housed in clear plastic. This device has a high luminous efficiency and a 950 nm spectrum suitable for silicon detectors. It is small and at the same time has a wide radiation angle, making it ideal for compact optical control equipment. |
