TLZ22B-GS18

Working Principle

The working principle behind a single Zener diode, such as the TLZ22B-GS18, is the same as that of any other diode. The device works by allowing large amounts of current to flow in one direction, while blocking it in the other direction. When a voltage is applied to the component, the current will only flow in the direction away from the anode (positive terminal) and toward the cathode (negative terminal). If the voltage across the diode exceeds the breakdown voltage, the diode will allow current to flow in both directions. This flow of current in both directions is known as Zener breakdown.

This breakdown is caused by the increased electric field strength in the region between the anode and cathode of the diode. This electric field causes electrons to be pushed from the valence band to the conduction band, which allows current to flow in both directions. This breakdown voltage is fixed for a given diode and will not change, even with variations in the power supply voltage.

The TLZ22B-GS18 single Zener diode is a type of component that is used in systems where voltage regulation is necessary. It is made with a lead frame and an enclosed structure to ensure that it is protected from external influences. The component has a breakdown voltage of 18V, a maximum power rating of 500mW and a maximum reverse voltage of 22V. The working principle of the component is based on the Zener breakdown that occurs when a voltage greater than the breakdown voltage is applied to the diode.
