uni junction transistor
if a diode is in forward biased the diode acts as switch is on and when we apply the diode in reverse biased then it work as the switch as off.
A: a semiconductor conducts one way only
The Anode. Think of the arrow like a Capital Letter A standing for the Anode.
The primary difference is that a semiconductor diode is a diode with a p-n junction, and a light-emitting diode is a special case or special type of semiconductor diode that emits light when it is forward biased.
A put diode is a type of semiconductor device that allows current to flow in one direction while blocking it in the opposite direction, similar to a standard diode. However, the term "put diode" may be a typographical error or confusion with "put option" in finance or other specific diodes like "Zener diode" or "Schottky diode." If you're referring to a specific application or context, please clarify for a more accurate explanation.

acts like a normal diode in forward biased condition
A diode is semiconductor device which is used in a lot of application in electronics equipment.it is negative temp. coefficient device i.e. at lower temp. it is behave like a insulator and high temp. it is work like a good conductor. Basically a diode is used to convert an alternating current into direct current in form of a rectifier. There are many types of diode used in today day to day life depends upon their application. 1 crystal diode 2 photo diode 3zener diode are some of the most useful diode.

A light emitting diode is a special type of diode made of transparent semiconductor (silicon & germanium are opaque) like aluminum indium gallium phosphide. The selected semiconductor must also have a large enough band gap that when electrons fall into holes photons are emitted.
when a semiconductor is doped with p-type and n-type impurities, a pn junction is formed which acts as a diode and prevents the charge carriers to flow to either side of junctionpn juction diode is a semiconductor device that allows current to flow only to one direction.
An ordinary semiconductor diode uses a P-N junction, but when reverse biased it takes a period of time to remove the current carriers from that junction to create the depletion region that blocks reverse conduction. A Shockley diode instead uses a P semiconductor-metal junction, which removes the current carriers much faster from the semiconductor allowing the device to switch much faster. It also has a much lower forward bias voltage than an ordinary diode. In many ways it is similar to the previous point contact diodes (a piece of semiconductor like galena or germanium with a metal "cat's whisker" point contact) in operation, but is more reliable and easier to mass produce.

Like a normal diode............. unless it includes a "back biased" diode to prevent conduction in this mode as is common in zener diodes rated at about 10 volts or more, then it acts as an open circuit.
