TV02W141-HF is a Uni-directional TVS-Diode, which combines ESD protection with high surge current capability. This type of components provides protection for voltage sensitive components against electrostatic and transient overvoltage. It is composed of two series connected PN junctions and a high temperature Zinc Oxide (ZnO) varistor between the two junctions.

Application Field:

As a TVS-diode, the TV02W141-HF offers protection from ESD and other transitory voltage that can cause product damage. Such component is used in a variety of applications, from electrical and electronic devices to automotive components. It provides multi-level protection, and can be used for a range of external and internal power lines, as well as I/O interfaces.

Working Principle:

A TV02W141-HF consists of two series connected PN junctions and a high temperature Zinc Oxide (ZnO) varistor between the two junctions. The PN junction is built from silicon-zinc Oxide sandwiches that has high dielectric electrical characteristics. In reverse bias, the TVS-diode offers a high level of protection against ESD. The ZnO varistor offers protection from transient overvoltage. When a surge voltage is applied to the junctions in reverse bias, it will cause the electric field to increase, allowing electrons to move from the p-side to the n-side. The electrical flow is regulated by the ZnO varistor, which helps regulate the voltage variation. When the transient current exceeds the levels established by the ZnO, the device will break down and block the excessive current.

Conclusion:

The TV02W141-HF is a Uni-directional TVS-diode that offers many advantages for protecting against voltage sensitive components from ESD and other overvoltage conditions. It is used in many different products, and provides multi-level protection for external and internal power lines, as well as I/O interfaces. It works by utilizing two series connected PN junctions and a high temperature ZnO varistor that regulates the electric field.
