Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.

What is the forward biased knee voltage for a 1n4001 silicon diode?
A; The 1N4xxx series of rectifier diodes are specified as 1 amp forward conduction. the last number signify the maxi mun reverse voltage it can sustain without breakdown.
What is zener break down voltage?
The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.-- Dinakar
Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What is 0.37v and 0.63v in RC circuit?
0.63 is the knee voltage & 0.37 is the cutoff voltage
What happens to the current when the voltage becomes limited at the knee?
A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature
What is knee voltage and breakdown voltage?
Knee voltage (cut in voltage) :-The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage Breakdown voltage :-It is the minimum reverse voltage at which the P-N Junction can conduct without damage to the current
What is the value of the knee voltage and breakdown voltage of z?
It is about 0.7 volt for Silicon diodes.
What is the zener breakdown voltage?
A: 6.2 volts for zeners are very sharp. Lower then that the knee is sloppy and above the sharpness decreases. A 3,2 v zener maybe nothings more then diodes in series, The sharpness of the knee is more pronounced into Vbe breakdown of transistors however the voltage cannot be predicted

What is meant by cut in voltage in diode?
Cut in voltage (Knee voltage): The forward voltage at which the current through the P-N Junction starts increasing rapidly is called as Cut in voltage or knee voltage.
What does it means when we say-diode is specially designed to operate under reverse bias in breakdown region?
You are talking about a special type of diode called a zener diode which is designed, using special junction doping, to allow controllable reverse bias operation at a reduced breakdown voltage with a much sharper knee point curve than its normal forward breakdown curve. This allows the diode to be used as a voltage regulator. Normally, a diode's reverse breakdown curve is such that, at reverse breakdown, it avalanches and, without current limits in place, will self destruct. The zener diode, on the other hand, will operate in reverse much the same as it does in forward, just at a different voltage, and with a much sharper current to voltage curve, making it highly suitable as a voltage regulator.
Knee pont voltage- briefly distinguish?
The knee point voltage of a CT is the voltage at the "knee" of a I-V characteristic (if you increase voltage, and plot this voltage with respect to the current flow, you will see a logorithmic type response). The knee is usually specified as 10% distortion (ie, the voltage is 10% less than you would expect relative to the current flow). beyond the knee point, the CT is considered in saturation. This applies to amplifiers / transistors as well as CTs. Transistors used as ampifiers are operated in the "linear region", or the region below the knee point of that particular transistors I-V characteristic.
Cut in voltage?
The forward voltage at which the current through the junction starts increasing rapidly, is called the knee voltage or cut-in voltage.
What is 0.37v and 0.63v in RC circuit?
0.63 is the knee voltage & 0.37 is the cutoff voltage
Why silicon is preferred over other materials in designing ic?
because1) knee voltage of silicon is .7V where as germanium has .3V 2)silicon breakdown take place at around 200 0C and germanium at 90 0C
Why the knee voltage for germanium is 0.2v?
That is the property of that material.
