Sådan en stabiliseret spændingskilde har dog en begrænsning i den strøm man kan trække fra den: Trækker man "for meget" strøm, falder Avalanche diodes are optimized for avalanche effect so they exhibit small but significant voltage drop under breakdown conditions, unlike Zener diodes that always maintain a voltage higher than breakdown. This category has the following 3 subcategories, out of 3 total. Because it can be built with a known breakdown voltage, it can be used to accurately measure voltage. (Weitergeleitet von Zener-Diode). Zener diode is like a normal diode, but instead of being destroyed by a big reverse voltage, it lets electricity through.The voltage needed for this is called the breakdown voltage or Zener voltage. Khi đó giá trị điện áp ít thay đổi. Ini berlainan dari diode biasa yang hanya menyalurkan arus listrik ke satu arah. Reasonator; PetScan; Scholia; Statistics; Search depicted; Subcategories.

Wikipedia: Subclass of: p–n diode: Named after: Clarence Zener; Authority control Q180586 GND ID: 4190693-7.

Systemet balancerer sig selv ved det punkt, hvor der lige netop er zenerspændingen hen over dioden. Wikipedia is hosted by the Wikimedia Foundation, a non-profit organization that also hosts a range of other projects. Elle maintient ensuite la tension à … This feature provides better surge protection than a simple Zener diode and acts more like a gas discharge tube replacement. Die Höhe dieser Durchbruchspannung U BR ist die Hauptkenngröße einer Z-Diode und ist im Datenblatt spezifiziert.

Nó được chế tạo sao cho khi phân cực ngược thì điốt Zener sẽ ghim một mức điện áp gần cố định bằng giá trị ghi trên diode, làm ổn áp cho mạch điện. Zener diode is like a normal diode, but instead of being destroyed by a big reverse voltage, it lets electricity through.The voltage needed for this is called the breakdown voltage or Zener voltage. Diode Zener adalah diode yang memiliki karakteristik menyalurkan arus listrik mengalir ke arah yang berlawanan jika tegangan yang diberikan melampaui batas "tegangan tembus" (breakdown voltage) atau "tegangan Zener". Điốt Zener còn gọi là điốt ổn áp, là một loại Điốt bán dẫn làm việc ở chế độ phân cực ngược trên vùng điện áp đánh thủng. Eine Z-Diode (früher auch Zener-Diode) ist eine Diode, die darauf ausgelegt ist, dauerhaft in Sperrrichtung im Bereich der Durchbruchspannung betrieben zu werden.

Lorsqu'on la connecte en inverse en parallèle avec une source de tension variable, une diode Zener devient conductrice lorsque la tension atteint la tension d'avalanche de la diode.

Because it can be built with a known breakdown voltage, it can be used to accurately measure voltage. Parallelforbindelsen af dioden og Ra, vil lede strøm og giver et spændingsfald over modstanden Rv, hvorved spændingen over dioden stort set bibeholdes. Les diodes Zener sont fréquemment utilisées pour réguler la tension dans un circuit.
