TZX12A-TR

Diodes - Zener - Single: TZX12A-TR Application Field and Working Principle

The TZX12A-TR is a Zener (diode) single that has rapid avalanche characteristics along with very low leakage and voltage regulation capability. The rated V_Z (Zener voltage) of this device is 12V, making it a nice choice for a variety of applications.

The TZX12A-TR is a great choice for noise suppression and surge protection in applications such as power supply circuits and motor control circuits. Its low leakage feature is ideal for the protection of semi-conductors such as MOSFETs and IGBTs. Additionally, the Zener single can be used in voltage level switches and voltage regulators. This makes it a great choice for applications where the input voltage needs to be regulated and/or stabilized.

TZX12A-TR Working Principle

The working principle of the TZX12A-TR is based on the Zener effect. This is the phenomenon where the electric current passing through a diode changes with an applied voltage. In the case of the TZX12A-TR, the Zener voltage V_Z is 12V, and when a voltage above the Zener voltage is applied from the anode terminal to the cathode terminal, the electric current will start to flow from the anode to the cathode.

As the reverse voltage continues to increase, the diode will start to conduct the electric current more - this is the avalanche breakdown. The reverse current (lease current) will remain constant regardless of the increasing voltage, and voltage levels equal to, or higher than the rated V_Z, will be clamped (or stabilized) at a certain level. This stabilization of the current is what makes the TZX12A-TR great for voltage level switches and voltage regulators.

Conclusion

The TZX12A-TR is a great choice for applications such as power supply circuits and motor control circuits, due to its rapid avalanche characteristics, low leakage, and voltage regulation capabilities. Additionally, the Zener single can be used in voltage level switches and voltage regulators for its ability to stabilize currents and provide a constant voltage level. With its great features, the TZX12A-TR can easily be used in a variety of settings.
