What is a Zener diode used for in a circuit?
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. Voltage regulator. The load voltage equals breakdown voltage VZ of the diode.
How do you know if a Zener diode is 4148?
Generally you can tell because a 1N4148 is typically marked ‘1N4148’ on the body, while a Zener diode has a different marking. You may need a magnifying glass to make sure though, because other diodes can have quite similar markings. If the markings are partially rubbed off it might be difficult to tell the difference.
What is a 1N4148 diode made from?
1N4148 is a standard diode made up of silicon and is used for extremely fast switching operations. It has two modes of operation named as: Forward Biased. Reverse Baised.
How do you read a zener diode?
The negative or black lead of the multimeter should be on the cathode or marked side of the diode. A forward-biased silicon diode should read 0.5 to 0.7 volts, so this is the reading you should see for the zener. To test the reverse-biased voltage, switch the multimeter leads.
What is the most common use for a Zener diode?
voltage references
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode’s reverse breakdown voltage.
What is special about Zener diode?
A Zener diode not only allows current to flow from anode to cathode but also, in the reverse direction on reaching the Zener voltage. Due to this functionality, Zener diodes are the most commonly used semiconductor diodes.
Is 1N4007 fast?
The 1N4007 is also approximately 1000 times slower, so in many applications it is an unsuitable replacement for a fast switching diode such as the 1N4148. In this case, as timorr says, it should be okay.
