99912 applications voltage stabilization 3 d d 3d models notes. the zener diode is fabricated from the element silicon ( si). discuss zener diode is one of the most important semiconductor diodes used in our daily life. zener diodes are simple and useful devices for building voltage regulator circuits, but are times when you may have to improvise in the absence of the proper zener diode. by using an led and a zener diode we can create a circuit which gives turns on the led when a voltage exceeds a certain value. 8, 25- nov- 2 document number: 85604 for technical questions within your region: com, com, com named for clarence zener, discoverer of this electrical property. it is a specific diode that works in reverse bias conditions. a zener diode is a special type of diode designed to reliably allow current to flow " backwards" ( inverted polarity) when a certain set reverse voltage, known as the zener voltage, is reached. the zener diode operates just like the normal diode when in the forward- bias mode, and pdf has a turn- on voltage of between 0. 7v cvd junction model diode breakdown. 071 spring, chaniotakis and cory 6. 1n5221 to 1n5267 www. fiore via source content that was edited to the style and standards of the libretexts platform; a detailed edit history is available upon request.
5 6 1n4738a zener diode 9. tolerance and voltage designation ( v z) the type numbers shown have a standard tolerance of ± 5% on the nominal zener voltage, c for ± 2%, d for ± 1%. 1 28 < 5 7 1n4739a zener diode 10 25 < 7 0. 5 4 1n4736a zener diode 7. 1 49 < 7 < 550 1n4733a zener diode 5. 2) maximum zener current ratings ( izm). let’ s learn about zener diodes their function, and their construction, in detail in this article. zener diodes 1n4728a - 1n4758a absolute maximum ratings ( note 1) ta = 25 ° c unless otherwise noted stresses exceeding those listed in the maximum ratings table may damage the device. a zener diode, also referred to as a breakdown diode, is a specially doped semiconductor device engineered to function in the reverse direction. it allows current to flow from anode to cathode and it also works in the reverse direction. very sharp reverse characteristic. stability and accuracy is generally good enough for the zener diode to be used as a voltage regulator device in common power supply circuit in figure below. please take note of the zener diode' s orientation in the above circuit: the diode is reverse- biased, and intentionally so.
