Some devices labeled as high-voltage Zener diodes are actually avalanche diodes (see below). The difference between the avalanche diode (which has a reverse breakdown above about 6.2 V) and the Zener is that the channel length of the former exceeds the mean free path of the electrons, so there are collisions between them on the way out. Gerald Buller is Principal Investigator-designate (2021-2024) and has worked in single-photon physics and applications since 1990, being a very early adopter of silicon single-photon avalanche diode (SPAD) detectors. Zener and avalanche diodes, regardless of breakdown voltage, are usually marketed under the umbrella term of "Zener diode". Martin Wendel - Related organizations: Infineon Technologies Ag patents. The Shockley ideal diode equation or the diode law (named after transistor co-inventor William Bradford Shockley) gives the I–V characteristic of an ideal diode in either forward or reverse bias (or no bias). While PIN photodiode technology has been the most widely used format for diodes, other types including the avalanche diode were also demonstrated. These are electrically very similar to Zener diodes, and are often mistakenly called Zener diodes, but break down by a different mechanism, the avalanche effect.

SBDs are not made using the principle of forming a PN junction between a P-type semiconductor and an N-type semiconductor but are made using the metal-semiconductor principle formed by the contact between a metal and a semiconductor. These are electrically very similar to Zener diodes, and are often mistakenly called Zener diodes, but break down by a different mechanism, the avalanche effect. Many early inventions were made till 1905, yet a more focused work on semiconductor devices were started only at the time of the Second World War. This reverse voltage finds its way through the MOSFET's body diode, and if its value exceeds the device's maximum tolerable limit, causes intense heat to develop within the device causing harm or a permanent damage to the device.
