Voltage Current Characteristics of Diode
The V-I characteristics of a diode as shown in the figure show that When forward-biased, the diode begins to conduct current as the voltage across its anode is increased
Diode Protection
A power diode must be protected against over-voltage, over-current and transients.
Diode Circuit Analysis & Losses
To analyze diode circuits, the state of the diode (on or off) must first be found. The diode can then be replaced by the switch equivalent circuit.
Principal Ratings Of Diode
Principal Ratings Of Diode, Peak Inverse Voltage, Maximum Average Forward Current, Reverse Recovery Time, Maximum Junction Temperature, Maximum Surge Current
Diodes in Series
The maximum power that can be controlled by a single diode is determined by its rated reverse voltage and by its rated forward current.
Diodes In Parallel
If the load current is greater than the current rating of a single diode, then two or more diodes can be connected in parallel
Zener diodes
Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they
Vacuum Tube Diode
A Vacuum tube diode is a two electrode vacuum tube as its name shows DI for two ODE for electrodes. The two electrodes are cathode and anode (plate).
Tunnel Diode
This diode was first introduced by Dr. Leo Esaki in 1958. It is called a tunnel diode because due to its extremely thin depletion layer,
Formation of Depletion Layer in Diode
There is greater concentration of holes in P-region and electrons in N-region. This difference in concentration
Three Phase Full Wave Rectifier Using Six Diodes
In this circuit six diodes, Q3 transformer whose primary delta winding and secondary is star winding is used.
LED – Light Emitting Diode
A type of diode that emits light when there is forward current. The back operation of the LED is as follow.
Varactor Diode Modulator
Fig (b) shows the basic concept of a varactor frequency modulator. The L1 and C1 represent the tuned circuit of the carrier oscillator.
Diodes
Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow.
