Jänniteriippuvaisia

Jänniteriippuvaisia is a Finnish term that translates to "voltage-dependent" in English. It is commonly used in the context of electrical and electronic engineering to describe components or phenomena whose behavior or properties change based on the applied voltage.

For instance, certain electronic components exhibit voltage-dependent behavior. A prime example is a varistor, an electronic component whose resistance decreases as the voltage across it increases. This property makes varistors useful for surge protection, as they can absorb excess voltage by becoming more conductive. Similarly, semiconductor devices like diodes and transistors can have characteristics that are significantly influenced by the voltage applied to their terminals. The threshold voltage of a transistor, for example, is a critical parameter that determines when it begins to conduct.

In a broader sense, the term can also refer to physical phenomena that are triggered or altered by electric potential. For example, the dielectric strength of an insulating material, which is the maximum electric field it can withstand before breaking down, is essentially a voltage-dependent limit. When the voltage across an insulator exceeds this limit, the material can become conductive, leading to electrical breakdown. Understanding these voltage-dependent characteristics is fundamental to designing safe and reliable electrical systems and electronic circuits.
