The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas.

Similarly, the diode will conduct current once the flooded electrons and holes reach an equilibrium point, where the number of electrons is equal to the number of holes in the intrinsic region.

When the diode is forward biase the injected carrier concentration is typically several orders of magnitude higher than the intrinsic .

The photo detection occurs within the depletion area of the diode.

As this is relatively small, the sensitivity is not as great as that for some other forms of photo diode. To overcome this problem, we need to apply external energy directly to the depletion region to generate more charge carriers. A special type of diode called photodiode is designed to generate more number of charge carriers in depletion region. In photodiodes , we use light or photons as .

Photosensors or photodetectors are sensors of light or other electromagnetic energy. The absorbed photons make electron–hole pairs in the depletion region. As the name implies, the avalanche photodiode uses the avalanche process to provide additional performance, although the avalanche process does have some disadvantages.

Series 6: IR photodiodes with minimal dark current. High-performance PIN photodiodes for low-capacitance light detection as well as for alpha, beta, gamma and X-ray radiation detection. Due to its water clear epoxy the device is sensitive to infrared radiation. The mini-lens type photodiode can be efficiently coupled to an optical fiber. Package category, TO-1 with lens.
