Diodes - Zener - Single

BZX55A22-TAP is a single Zener diode, composed of semiconductor materials such as Germanium, silicon and germanium silicon. It is mainly used in the field of power supply and voltage stabilization.

Application Field

The BZX55A22-TAP is a high-voltage, medium-power zener diode with a zener breakdown voltage of 22V. It is mainly used in power supplies, voltage stabilizers and electronic circuits requiring voltage stabilization and temperature compensation. In addition, it can also be used in converting AC to DC rectification circuits, reverse peak-current protection in automotive electronics, and switching power supplies.

Working Principle

The BZX55A22-TAP is a Zener diode composed of semiconductor materials. When the voltage on the anode is greater than the Zener voltage of the diode, the diode enters the Zener breakdown state and the current in the diode increases sharply, forming a stable current. This process prevents further increases in the voltage on the anode.

When the voltage on the anode is greater than the Zener voltage of the diode, a large amount of energy is released in the diode. This energy is used to create additional electron-hole pairs and heat. This additional energy allows the diode to remain in its breakdown state, even when the circuit voltage on the anode drops below the Zener voltage.

When the opposite current is applied, the BZX55A22-TAP will act as a normal diode and block the opposite current, but it can still control the in-formed voltage due to its Zener breakdown voltage.

Advantages

The BZX55A22-TAP is a high-power, form-stable Zener diode that can be used in any application requiring a stable voltage level. It has a low power dissipation and can be used in high-frequency switching power supplies. It can be used in automotive reverse peak current protection circuits, thereby helping to reduce the risk of damage to electronic components.

The BZX55A22-TAP also has good temperature stability, which makes it suitable for applications that require precision voltage regulation. The reverse leakage current of the diode is very low, making the BZX55A22-TAP highly reliable.
