It will conduct electricity when the voltage across its terminals reaches a certain value. Once the over voltage is extinguished, the protection diode becomes an open circuit again.
Therefore, you need to connect a protection diode between both wires to be protected (differential mode) and from each wire to ground (common mode).
Protection diodes are primary protection devices (fast reacting), but they cannot handle too much current. That is why they need to be used with secondary protection devices (fuses and gas arrestors) to provide better protection.

What do you call a diode installed across a coil with the cathode toward the battery positive?
A diode connected in this way is a flyback diode or kickback diode. There are some other names that may be applied. The diode is a protection device. When power to the coil is discontinued, the electromagnetic field around the coil will collapse. The collapse of that field will induce a voltage, and this could expose circuit elements to "kickback" from the field collapse. The polarity of the induced voltage will, however, forward bias the diode, and it will conduct current for an instant. The inductive kickback of the coil will thus be damped by that diode.
What is a large slower acting diode?
it is a rectify diode
What is schotty diode?
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
What is the difference between a 1N4007 diode and a 1N4007S diode what does the s do?
The difference in the 1N4007 diode and the 1N4007S diode is the voltage. The 1N4007S has a higher voltage but the meaning of the S is not listed.
Can a diode power a circuit?
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
What is the protection of over current to a diode?
we use fuse only .thanks

If you were to swap the polarities of a diode would this circuit still operate Elaborate on your answer.?
It isn't clear what circuit you are talking about - and not even what sort of diode you are talking about. But in general, a diode might NOT work the same if you swap the polarity. For instance, a common diode is the rectifier diode; this one lets current through in one direction, but not in the other.Some diodes may even burn out if you connect them with the wrong polarity (and don't have adequate protection in place).
What is breakdown diode?
a break down diode is a diode that allows current to flow freely in one direction but not in the other the difference between it and a standard diode is that it is a semiconductor in the direction that current doesn't flow freely in current only flows in this side when the voltage reaches a set point and the resistance then breaks-down and allows the current to flow it is useful where the circuit might require low voltage protection
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 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
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is impatt diode?
The read type diode are called impatt diode
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
