Description:
Each of these devices consists of a NPN silicon phototransistor mounted in a miniature SMT package with a 0805 size chip carrier that is compatible with most automated mounting and position sensing equipment.
Both OP500, OP500DA and OP501, OP501DA have a flat lens. OP501 and OP501DA has an opaque lens that shields the device from stray light, whereas OP500 and OP500DA has a water clear lens. All devices have a wide viewing acceptance angle and higher collector current than devices without lenses especially on the OP500DA and OP501 which incorporate photo darlington die instead on the standard transistor.
OP500, OP501, OP500DA and OP501DA are mechanically and spectrally matched to the OP200 series infrared LEDs.
