Diode Knee Voltage
Knee voltage?
What's knee voltage, and why do diodes have knee voltages?
The knee voltage is the reverse voltage point where a Zener diode begins to conduct in the reverse direction. At this point the reverse current suddenly jumps from zero (or near enough zero) to a much higher value as the diode enters it's biased breakdown region.

Transmission Lines and Schottky Diode $108.33 A nonlinear relation between current and voltage for schottky resonant tunneling diode is used. A general form of equation similar to VanDer Pol equation is obtained. A Resonant tunneling diode(RTD) has a negative differential resistance that means when the voltage increases the current decreases. This property is very useful for oscillators manufacture. Nonlinear transmission lines is considered to show that it canbe used in oscillators and to show that it can reshape the sinusoidal signals to othershapes by using OrCad and mathematica programming.

Voltage Doubler $54.86 High Quality Content by WIKIPEDIA articles A voltage doubler is an electric circuit with an AC input and a DC output of roughly twice the peak input voltage. They are a variety of voltage multiplier circuit and are often, but not always, a single stage of a general form of such circuits. The term is usually applied to circuits consisting of rectifying diodes and capacitors only, other means of doubling voltages are not included.The Villard circuit consists simply of a capacitor and a diode. While it has the great benefit of simplicity, its output has very poor ripple characteristics. Essentially, the circuit is a diode clamp circuit.

Over Voltage Protector $61.95 Electronics of modern cars are at risk from voltage surges during a number of common daily jobs. Surges during MIG welding, jump-starting, battery charging and starting are just a few. Damage to systems such as Air Bags and ABS may not be immediately apparent, but could prove fatal. Engine management systems, fuel injection, radios, alarms and many other delicate electronics can be destroyed. You could be liable for damage to a customer?s vehicle. ? Equipped with an LED indicator to show that the unit is providing protection and installed correctly. If the unit is overloaded or damaged, the light will go out. ? Gives greater protection than other comparable units. ? Features a heavy-duty varistor, not a small diode insuring maximum protection and maximum peace-of-mind.By Dent Fix Equipment. |

Zener diodes and Zener breakdown?
Simple question, is there a difference between the "zener breakdown voltage" and the "reverse breakdown (knee) voltage"? That's how it's stated in my lab manual. It seems these are the same, what's the difference?
if we are considering a zener diode, which will be greater, the knee voltage or the zener voltage? what is their relationship to one another?
The zener breakdown voltage and the reverse breakdown voltage of a diode are the basically the same thing. A zener diode is built to have a predictable breakdown voltage while the reverse breakdown voltage of diodes that are not meant to be used as zener diodes will vary considerably, but will all be greater than the specified breakdown voltage. Reverse breakdown in a diode is non-destructive as long as the amount of power dissipated is limited.
