What is a reverse diode?
is an electronic device that controls the direction of the current flow in the circuit. The standard diode allows the power flow forward, but not in the opposite direction. However, one type of diode can under certain conditions perform the current in the opposite direction. This special diode type is a reverse diode.
The diode design includes two semiconductor material segments such as silicon. One segment has a positive charge called anode. The second segment has a negative charge called cathode. In production, these two segments are fused together and create a PN intersection that identifies one part as positive and the other as negative. Metal wires are then usually connected to the end, opposite the intersection, to form a diode. When the two segments of the material are connected together, they cancel each other's electric charge in a narrow band through the intersection of the pnoblast of exhaustion. This diode area of the latest neither positive nor negative electric charge and acts as an insulator between two diode segments.
In normal operation, the diode works similar to an electronic control valve. If a negative voltage is applied to the diode cathode, the charge is combined with an internal electric diode. When this happens, the insulation of the depletion area at the PN intersection holds, which prevents the electric current in the passage through the diode. The diode working in this state is in the reverse diode operation or reverse distortion.
However, if negative voltage is applied to the anode of the diode, the voltage moves into a positive part of the diode. When it reaches the intersection, the charge will have enough electricity to bridge the area of exhaustion. At this point, the diode will perform the electrical current allow to continue the flow until the voltage is removed. LEDs working in this state are in the forward operation or forward.
, however, the depletion area can withstand only a certain level of voltage. If the voltage was too high when the device workIt is in the reverse diodes, the depletion area fails and allows you to go through the increase in electricity. This phenomenon is called an avalanche and when it occurs, it usually destroys a standard diode.
While the avalanche phenomenon is generally to avoid, engineers have found that voltage blocking until it reaches a predetermined level, and then allows it to pass, could be a useful tool in the development of electronic technologies. Then they began to design diodes with very specific depletion areas that would withstand the terrible effects of the avalanche. Since their establishment, these types of diodes have entered virtually every field of electronics.
In operation, the reverse diode acts as a standard diode. A negative voltage is applied to the cathode and the diode blocks it. However, if this voltage continues to increase to a predetermined level, called decomposition voltage, the diode undergoes an avalanche and begins to safely perform electric current in the opposite direction. These diodes pass through many names, including avalancheEducation of diodes, decomposition or reverse diodes.
