Avalanche photodiode detectors (APD) have and will continue to be used in many diverse applications such as laser range finders, data communications or photon correlation studies. Avalanche photodiodes (APDs) APDs are photodiodes with internal gain produced by the application of a reverse voltage. An avalanche diode is a one kind of diode that is designed to experience an avalanche breakdown at a particular reverse bias voltage. When the reverse biased voltage is applied to the avalanche diode, then the majority charge carriers in the P-type and N-type semiconductors are moved away from the PN- junction.

Impact ionization is a non-radiative process, where an energetic electron or hole, collides with an electron in the valence band, creating an electron-hole pair. This junction breakdown is named as an avalanche breakdown. Avalanche Photodiodes ( APDs ) are high sensitivity, high speed semi-conductor "light" sensors. APD Current Monitor (Figure Center) Operates at High Common Mode Voltage, Complicating Signal Conditioning. In this regime, carriers (electrons and holes) excited by absorbed photons are strongly accelerated in the strong internal electric field, so that they can generate secondary carriers. A diode is a two terminal electrical component used to build various electrical and electronic circuits.

Road traffic is becoming safer, more efficient, and more autonomous. These huge number of free electrons hold overload current in the diode. Application Note 92 AN92-2. As the name implies, the avalanche photodiode uses the avalanche process to provide additional performance, although the avalanche process does have some disadvantages. Again, these electrons are accelerated. When the voltage in reverse bias condition applied to this diode then it surpasses the breakdown voltage, a breakdown of the junction will be occurs.
