Silicon Phototransistor in SMT
Plastic Package
OP580
Wide Acceptance Angle
Fast Response Time
Plastic Leadless Chip Carrier (PLCC)
The OP580 is an NPN silicon phototransistor mounted in a miniature SMT package. The device has a flat window
lens which enables a wide acceptance angle. This device is packaged in a plastic leadless chip carrier that is
compatible with most automated mounting equipment. The OP580 is mechanically and spectrally matched to the
OP280 infrared LED.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
