Dual-Photodiode with a common anodePREMA IC PR5010

PR5010 is a double silicon photodiode with two symmetrical anodes and a common cathode, sensitive for visible light. The cathode forms an additional photodiode to the substrate that is sensitive for infrared light.
Key features are the low dark current combined with a high sensitivity and an antireflective coating on the die. PR5010 is available in an optical DFN package with a very small formfactor.
