Deze eigenschap berust op het zenereffect. De karakteristiek van de diode verloopt over dat bereik min of . Normal diodes will also break down with a reverse voltage but the voltage and . Zener diodes have a highly doped p-n junction. De spanning-karakteristiek van de diode verloopt over dat . Pas in sperrichting onderscheidt de zener zich van een normale diode. Een zenerdiode in geleiding gedraagt zich als een normale diode.
Kijk eens naar het onderstaande schema. Hierin zien we een zenerdiode in sperrichting. If we connect a diode and resistor in series with a DC voltage source so that the diode is forward-biase the voltage drop across the diode will remain fairly constant over a wide range of power supply voltages as in Figure below (a).
According to the “ diode equation” here, the current through a forward-biased PN junction is . The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached. A tutorial on zener diodes and how to use them as voltage clamps, voltage regulators, and how to create audio. They are available with power ranges from less than 3mW to over 5mW and include a number of automotive- qualified parts.
Products include the 5mW PLZ series, which features a MicroMELF . Zener Diodes are available at Mouser Electronics. V 5mW Through Hole 2-Pin DO-35BZX79- B5Vor other zener – diodes online from RS for next day delivery on your order plus great service and a great price from the largest electronics components. ON Semiconductor supplies zener diodes for voltage regulation circuits. A zener diode is a p-n junction semiconductor device that is designed to operate in the reverse breakdown region.
To construct a zener diode voltage regulator and measure its line and load regulation. When biased in the forward direction it behaves just like a . That means you apply voltage across them, and when a preset voltage is reache they start conducting. A common analogy is a pressure relief valve. They have lots of uses, especially in safety circuits where you want to make . These diodes are rated for 5. While offering a cheaper alternative to IC solutions, Zeners give you customize effective protection in small scale, high density circuit designs.
Staat je antwoord er niet bij of heb je een vraag waarbij het vertaalwoordenboek geen hulp kan bieden? Define zener diode : a silicon semiconductor device used especially as a voltage regulator. A semiconductor junction device through which current flows normally in the forward direction, and in the reverse direction if a large voltage is applied. Because of this unique characteristic, they can be placed in parallel across a load and used as a voltage regulator .
