OP521

SMD Silicon Phototransistor OP520, OP521 OP520, OP521 High Photo Sensitivity Fast Response Time 1206 Package Size Opaque or Water Clear Flat Lens Description: The OP520 and OP521 are NPN silicon phototransistor mounted in miniature SMT packages. Both the OP520 and OP521 have a flat lens however, the OP520 lens is opaque to shield the device from stray light. These sensors are packaged in 1206 size chip carriers that are compatible with most automated mounting equipment. The OP520 and OP521 are mechanically and spectrally matched to the OP250 series infrared LEDs.
