Two is Better than One: Photodiodes
Did you know that most of the electronic equipment used nowadays are powered by several electronic components? One of them is a semiconductor that converts light energy into electrical voltage or current. In our homes and offices, we use laser printers and laser scanners. Up the ceiling, there are smoke detectors. Go out and take a picture using a digital camera that also utilizes this small chip.
Prema Semiconductor’s newly released product series and best-seller, the Dual Photodiode PR5001. It is a dual-element Si photodiode molded into a small plastic leadless optical package. Produced as one chip, the photodiodes offer good symmetry, low dark current, and high sensitivity. This semiconductor device has a PN junction and operates in a reverse-bias condition.
PR5001-ARC version, on the other hand, features an anti-reflective layer, smoothing the spectral sensitivity and providing a good matching from part to part.
