The cathode terminal can be identified by using a grey bar as shown in the picture above. In circuit diagrams, a diode is represented by a triangle with a line across one vertex.. In PIN diode doping is not necessary. That is the current should always flow from the Anode to cathode. In the case when no large input signal is present, the impedance of the limiter diode is at its maximum, thereby 6. The diode acts like a switch which can be on or off. The PIN limiter diode can be described as an incident-power-controlled, variable resistor. See also AC, APD, DC, diode laser, FOTS, FSO, LED, PIN, and rectifier. Most of the photons are absorbed in the intrinsic region, and carriers generated therein can efficiently contribute to the photocurrent . An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a … PIN diode switches are often used to control the path of RF signals.

A Tunnel diode is a heavily doped p-n junction diode in which the electric current decreases as the voltage increases. The laser diode is quite different from the common perception of lasers as big, bulky and power-hungry devices that emit an intense beam of light that can burn or even cut. The advantage of a PIN diode is that the depletion region exists almost completely within the intrinsic region, which has a constant width (or almost constant) regardless of disturbances applied to the diode. Note: A PIN diode exhibits an increase in its electrical conductivity as a function of the intensity, wavelength, and modulation rate of the incident radiation. The resistance value of the PIN diode is determined only by the forward biased dc current. A p-n junction diode is a basic semiconductor device that controls the flow of electric current in a circuit. In other words, the diode which is specially designed for optimising the breakdown region is known as the Zener diode. Dictionary ! Read a bit more on PIN Diodes as part of the Radar Dictionary.
