What is the intersection?

and the intersection is a semiconductor crystal, usually made of silicon, with two electric terminals. The P-N Junction diode is the most common type of semiconductor diode. The connecting diodes usually make it easy to make a current easily in one direction, but not the other. The connection diodes can be used to change the AC current (AC) to direct current (DC), sensory temperature and protection of circuits from voltage damage. They can also create and capture light, create logical gates and perform many other features. Different types of connections such as radios, TVs and CDs are used in such devices, among many other electronic devices.

When a connecting diode is made, its crystal is implanted with positive wearers of P-Type called holes, on one side. The other side is implanted by the wearer of the N, which are electrons. In the meantime, the thin area is known as the P-N intersection. Some electrons walk around the intersection to connect with Holes andOn the contrary. This creates a narrow area of ​​the neutral charge around the intersection, called a layer of exhaustion.

When the forward voltage is across the connecting diode, it usually forces multiple electrons to the N region. It also forces more holes to the P area. As this voltage increases, the depletion layer narrows. This facilitates the flow of the flow over the intersection. Once the forward distortion exceeds a certain voltage, the current can flow quite easily.

If the opposite is applied, the reverse distortion voltage, may be from the P and more electrons from the N region. The holes and electrons are towed from the intersection and extend the layer of depletion. This usually makes the current flow. As the reverse distortion voltage increases, the current across the intersection slows almost zero. The remaining curr “leak” is often very small, but can increase with the diode connection temperature.

and the connecting diode has many uses related to Jeho the ability to carry a current in only one direction. For example, it can convert AC to DC, also known as rectification. It can also separate the audio signal from the radio frequency signal (RF) in the radio receiver. In the control circuits, the intersection diodes can offer power protection when the high current device, such as the engine or relay coil, is on or off. Many types of integrated circuits use diodes on each pin to prevent excessive external voltage in the chip damage.

The intersection diodes can be very sensitive to dark plastic light, in which they are usually closed. They are usually used as photodiodes to detect light and in solar cells to convert light into electricity. LED emitting diode (LED) is a connecting diode that generates photons. LEDs exist in different colors and can produce light from infrared to almost ult.aviolet. They are often used as state indicators also in electronic devices. Laser diode generates lightOne wavelength, which is usually focused on a polished cavity in its packaging. Laser diodes are often used in high -speed communication and CD/DVD consumer units.

Other connecting diodes include logical gates, keyboard nuts, temperature sensors and voltage controllers. The connecting diode may also act as a capacitor controlled variable voltage; The radio or television tuning circuit can change the size of the depletion layer, which in turn changes capacity.
