Theory The diode is a device formed from a junction of n-type and p-type semi-conductor material. The tunnelling is the phenomenon of conduction in the semiconductor material in which the charge carrier punches the barrier instead of climbing through it.

Diode Valve Characteristics Apparatus » SMPS Trainer Kit. From the I-V Characteristics curve we can study that the zener diode has a region in its reverse bias characteristics of almost a constant negative voltage regardless of the value of the current flowing through the diode and remains nearly constant even with large changes in current as long as the zener diodes current remains between the breakdown current and the maximum current rating . On the contrary, the concentration of electrons is lower. The concentration of impurity in the normal PN-junction diode is about 1 part in 10 8.And in the tunnel diode, the concentration of the impurity is about 1 part in 10 3.Because of the heavy doping, the diode conducts current both in the forward as well as in the reverse direction. However, unlike a resistor, a diode does not behave linearly with … Tunnel Diode Characteristics Apparatus. Magnascopes / Multipurpose Inspection Microscopes, Metallographic Cutters / Polishers / Grinders / Sample Mounting Presses. Email This BlogThis! Account & Lists Sign in Account & Lists Returns & Orders. Because of the thinness of the junction, the electrons can pass through the potential barrier of the dam layer at a suitable polarization, reaching the energy states on the other sides of the junction. The tunnel diode is used as a very fast switching device in computers. The Zener diode is like a general-purpose signal diode.

The tunnel diode amplifier/diode attenuator 12, when biased in the lossy position, is capable of handling large signal power levels without danger of diode burnout. A Tunnel diode is a heavily doped p-n junction diode in which the electric current decreases as the voltage increases. Tunnel Diode Characteristics Apparatus Technical Specifications : Inbuilt Fixed DC regulated power supply Output Voltage : +5VDC On Board Digital Panel Meter Digital panel meter for measuring V1 : Voltage across Resistance R 3 V2 : Voltage across Tunnel Diode Potentiometer & Diode Potentiometer : R1 (Current control) Tunnel Diode : IN 3717 High quality … Our range of products include air wedge - thickness of a thin wire( travelling microscope), tunnel diode characteristics apparatus, electric kettle apparatus, ujt charterstics apptratus, thermocouple trainer kit and solar cell characteristics apparatus. Posted by ASICO INDIA at 21:53. Thus, charge carriers do not need any kinetic energy to move across the junction; they simply punch through the junction.

It is fabricated using premium quality raw material and progressive machinery at our vendors’ unit in compliance with the industrial set norms and standards. The circuitry exhibits oscillatory behavior when its operating point is forced to an unstable region of the transfer function by means of manipulating the transfer function. When the voltage is first applied current stars flowing through it. While in heavily doped N-type semiconductor, the concentration of electrons is higher. Posted by shraddhavij11 at 23:22.
