Working principle

The BZX384B18-G3-18 follows the standard principle of single zener diode that is, when a current is passed through an N-type material, it makes holes in the material and comes out in the form of electrons. These electrons, which are negatively charged, then cross the junction and enter the P-type material of the diode. This creates an electric field and a potential barrier, which results in the current only flowing in one direction and not reversing.

The electrons then cross the junction and enter the diode, thereby establishing a reversal voltage. At this voltage, the diode’s internal resistance decreases, allowing more current to flow. This is known as the zener effect, and it allows the diode to maintain a constant voltage through the reversals in current.

Once the zener voltage of BZX384B18-G3-18 is reached, it will remain constant and will not be affected by the additional current. This is what allows the device to be used in various different applications and makes it an ideal choice for automotive, power supply, LED indicators and many other applications.
