Does zener diode works after breakdown voltage?
Yes. The intended use of a zener diode is to be reverse biased at the breakdown voltage. In this mode, the zener has high slope in the current to voltage curve, making it a good choice for voltage regulation.
What is the function of zener dioed?
The function of a zener diode is for it to act as a voltage regulator in the breakdown region.
Can you use a capacitor instead of zener diode in biased clipping circuit?
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
When operating as a voltage regulator the breakdown in a Zener diode occurs due to which effect?
avalanche
What is the voltage rating wattage and other specs of a 1ZB43BB zener diode you need one to fix your tv Sears wants 16 for one and if you knew the specs you could order one much cheaper Thanks?
The specs and the voltage rating for the 1ZB43BB Zener diode is not listed. One may have to directly contact the manufacturer.
How do you find the current rating of a zener diode if the power rating is 500mw and a voltage rating of 10v?
A zener diode with a rating of 500 mW will pass 50 mA at 10 V. (Power = voltage times current)Note: The question appears mis stated, in that it states a rating of 500 MW, not 500 mW. To my knowledge, there is no zener with a rating of 500 MW.
How much voltage appears across a zener diode when it is forward-biased?
That depends on the zener voltage rating:"low voltage" zeners are just a simple single diode, the zener diode"high voltage" zeners contain 2 back to back diodes in one package, the zener diode and an ordinary diode that is reverse biased when the zener diode is forward biased to block forward conduction of the zener and protect it from overcurrent damage if installed backwards by mistakeThus in "low voltage" zeners when forward biased they will have a normal diode drop (e.g. 0.7V), but "high voltage" zeners when "forward biased" they will act open due to the reverse biased blocking/protection diode in series with the zener.
How is the zener diode connected to protect the load?
A: A zener is a diode that if reversed voltage is applied will conduct at a certain voltage. This diode zener therefore will conduct at a preset voltage limiting the over voltage to the diode conducting voltage and no more so the load can see the voltage up to the zener voltage and no more because the zener will sink the extra current from over voltage situation.
Can zener diode used as rectifier?
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?
If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
Does zener diode works after breakdown voltage?
Yes. The intended use of a zener diode is to be reverse biased at the breakdown voltage. In this mode, the zener has high slope in the current to voltage curve, making it a good choice for voltage regulation.
