Wenn die spannung zwischen anode und kathode hoher ist als der spannungsabfall in vorwartsrichtung etwa 0 7 v leitet sie in vorwartsrichtung und leitet in umgekehrter richtung wenn die ruckwartsspannung gleich der zener spannung ist kann irgendein wert sein 12 v oder 70 v. Daher kann die zenor diode in beide richtungen fuhren.

A zener diode is a type of diode that allows current to flow in the conventional manner from its anode to its cathode ie.

Z diode anode kathode. When the current through the device is reversed the electrodes switch functions so anode becomes cathode while cathode becomes anode as long as the reversed current is applied with the exception of diodes where electrode naming is always based on the forward current direction. When the voltage across the terminals is reversed and the potential reaches the zener voltage or knee the junction will breakdown and current will flow in the reverse direction a desired characteristic. A simple zener diode circuit is shown below.

However you should keep in mind the convention that current direction is according to where a positive charge would move not a negative charge. In simple terms an electrode is a conductor that helps in establishing electrical contact with a. Energy coupling in a diode with a dielectric gridded cathode article pdf available in journal of applied physics 8863202 3207 september 2000 with 21 reads how we measure reads.

As nouns the difference between anode and diode is that anode is electricity an electrode of a cell or other electrically polarized device through which a positive current of electricity flows outwards and thus electrons flow inwards it usually but not always has a positive voltage while diode is an electronic device that allows current to flow in one direction only. For a 1n4732a zener diode the value of v z is 47v and p z is 500mw as mentioned in specifications above now with supply voltage vs of 12v the value of rs will be. The opposite of an anode is a cathode.

In the above circuit the formulae to calculate the zener series resistor rs is shown below. When the anode is positive with respect to the cathode. Before we learn about cathode and anode we need to first understand what an electrode is.

So if electrons do the actual moving in a cell then current runs the opposite direction. The anode and cathode are defined by the flow of currentin the general sense current refers to any movement of electrical charge. As per the general definition an electrode is a substance that helps in the conduction of electricity wherein the electric current either enters or leaves the non metallic medium like an electrolytic cell.
