Descriptions:
The OP520DA and OP521DA are NPN silicon photo darlingtons mounted in miniature 1206 SMD packages. Both the
OP520DA and OP521DA have a flat lens however, the OP520DA lens are opaque to shield the device from ambient light
unlike the lens of the OP521DA. These sensors are packaged in compact 1206 size chip carriers that are compatible with
most automated mounting equipment. The OP520DA and OP521DA are mechanically and spectrally matched to the OP250
series infrared LEDs.
Since these devices have a flat window lens, they enable a wide acceptance angle. It is packaged in a plastic leadless chip
carrier which is compatible for new applications with that need smaller dimension packages for automated mounting and detec-
tion equipment with new innovative designs. OP520DA and OP521DA are 100% production tested using infrared light for
close correlation with Optek GaAs and GaAlAs emitters. Photo darlington devices are normally used in application where light
signals are low and more current gain is needed than in comparison to the standard phototransistors.
