Zenerjännitteeksi

Zenerjännitteeksi is a Finnish term that translates to "Zener voltage" in English. It refers to the specific reverse voltage at which a Zener diode begins to conduct significant current. This characteristic voltage is a fundamental property of a Zener diode and is determined by its doping levels. When a Zener diode is subjected to a reverse voltage that reaches or exceeds its Zener voltage, a process called Zener breakdown occurs, allowing current to flow in the reverse direction.

This ability to maintain a relatively constant voltage across itself once the Zener voltage is reached makes Zener diodes invaluable for voltage regulation. They are commonly used to create stable reference voltages for other electronic circuits or to protect sensitive components from overvoltage conditions. The Zener voltage can vary widely depending on the specific diode, ranging from a few volts to hundreds of volts. When selecting a Zener diode for a particular application, it is crucial to choose one with a Zener voltage that matches the desired regulation level. The power rating of the diode is also important, as it indicates the maximum power the diode can dissipate without being damaged when conducting current at its Zener voltage.
