When looking across the discrete components in your electronic armory, it is easy to overlook the humble diode. After all, one can be forgiven for the conclusion that the everyday version of ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

One is laid bare by [WizardTim], as he cross-sections a 20KV high-voltage diode. A conventional low-voltage silicon diode has a forward voltage drop of about 0.7V and a relatively low maximum ...

Varactor diodes are two-terminal electronic components that are designed to provide voltage-controlled capacitance when operated under reverse bias. These simple semiconductors are PN junctions with a ...

Series troubleshooting: Bypass diodes fail regularly, either because they do not have a high enough power rating or because they are overloaded due to nearby lightning strikes. With the following ...

Light emitting diodes (LEDs) are PN junction devices that give off light radiation through electroluminescence when forward biased. They are used as various indicators in aviation, automotive and ...

The filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it and produces light as a result.
