Class Information
Number: 257/603
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Avalanche diode (e.g., so-called "zener" diode having breakdown voltage greater than 6 volts)
Description: Subject matter configured to operate in a manner in which an external voltage is applied in the reverse-conducting direction of the device junction with sufficient magnitude to cause the potential barrier at the junction to breakdown due to electrons or holes gaining sufficient speed to dislodge valence electrons and thus create more hole-electron current carriers by an avalanche process.
