Phototransistor, surface mount type
RPM-075PT
Quite new phototransistor which peak sensitivity is designed as same level as human eye. Best sensor to detect
illuminance. (Peak sensitivity is 600nm.) Small and light weight package which can be used for reflow soldering and Pd
free soldering.
!!!!Application
Control of lighting cellular phones, LCD displays, etc.
Control of strobe. (DSC, camcorder, etc.)
!!!!Features
1) Best sensor to detect illuminance.
(Peak sensitivity is 600nm.)
2) Small (2125) and light weight package (3mg) which
can be used for reflow soldering and Pd free
soldering.
3) Linear against wide range of illuminance from a few
Lx to 10000Lx over.
4) Use Si good for an environ ment. (not CdS)
!!!!Absolute maximum ratings (Ta=25°C)
