A PN junction (g1) An NP junction (g2) Another PN junction (g3) The symbol is similar to that of a traditional diode, with an anode and a cathode, but with an additional electrode, the gate. If a ...

The Gunn diode has hung around since its invention by J.B. Gunn in the early 1960s, and for good reasons. Even though it’s referred to as a “diode” because it has an anode and a cathode, it’s ...

Here, the P (cathode) and the N (anode) are joined in series, thus, we get three terminal pins: anode, gate, and cathode. When we forward bias the anode and cathode i.e. anode and cathode connected to ...

A 7-segment display is commonly used in electronic display devices for decimal numbers from 0 to 9 and in some cases, basic characters. The use of light-emitting diodes (LEDs) in seven-segment ...

Differences from other diodes and thyristors. Shockley diodes are a specific type of thyristor, but with a simpler structure and no gate for control. It relies solely on the voltage applied between ...

The PN diode. A diode’s function is to inhibit the flow of electric current in one direction while permitting it to pass through in the opposing direction. The essence of this theory lies in the ...

It has two points of contact, or terminals, called its anode and cathode. A diode’s primary purpose is to allow current to flow in only one direction. It achieves this using a p-n junction.

By design, it allows current to pass through it in one direction – from its anode (positive side) to its cathode (negative side) – while staunchly blocking any attempt of the current to flow in the ...
