High Photo Sensitivity
Fast Response Time
1206 Package Size with Internal Lens
The OP522 is an NPN silicon phototransistor mounted in a miniature SMT package. The device incorporates an
integral molded lens which enables a narrow acceptance angle and higher collector currents than devices without
lenses. This device is packaged in a 1206 size chip carrier that is compatible with most automated mounting
equipment. The OP522 is mechanically and spectrally matched to the OP250 series infrared LEDs.
