The material P6KE200A is broken. The main problem is to find out the reason of material breakage and then take corresponding solutions.
Diode, in electronic components, is a device with two electrodes, which only allows current to flow in one direction, and many uses are to apply its rectification function.
Varistors are used as electronically tunable capacitors. The current directionality of most diodes is usually called "rectification" function.
The most common function of diode is to only allow current to pass in one direction (called forward bias) and prevent current from passing in the opposite direction (called reverse bias).
Therefore, the diode can be considered as an electronic version of the check valve.
Diode, also known as crystal diode, is short for diode. In addition, there are early vacuum electronic diodes.
It is an electronic device that conducts current in one direction.
There is a PN junction and two lead terminals in the semiconductor diode. This electronic device has unidirectional current conductance according to the direction of applied voltage.
Generally speaking, crystal diode is a pn junction interface formed by sintering P-type semiconductor and N-type semiconductor.
A space charge layer is formed on both sides of the interface to form a self-built electric field.
When the applied voltage is equal to zero, the diffusion current is equal to the drift current caused by the self-built electric field caused by the carrier concentration difference between the two sides of the pn junction, which is also a normal diode characteristic.
