Many years ago I was using 2N918 transistors in an RF application. That transistor comes in a size TO-72 package, which has four leads, one each for the collector, the emitter, the base and the ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research ...
