Check out the written tutorial this is based on: www.circuitbread.com/tutorials/what-is-a-zener-diode-and-how-does-it-work - Susie did a great job and has more detail about Zeners and their specifications. Enjoy and have a great day!
How does a higher doping concentration reduce the width of the depletion region? And why would a thinner depletion region have more intense electric field?
The more intense electric field is similar to how a capacitor works. The closer the two plates are to each other, the greater the capacitance as the charges on the two plates can interact with each other more strongly via their electric fields. As for why the higher doping concentration reduces the width of the depletion region, I need a bit of a refresher myself, so I'm hoping I'll explain this correctly. At greater doping concentration there are more holes/free electrons on their respective p/n sides. As the holes and electrons are diffusing and crossing the junction to the other material, they run into their counterpart on the other side faster and reunite more quickly. This builds the charge faster and brings the junction to equilibrium with less real estate.
Technically, I don't see why not. Practically, you'll be losing HUGE amounts of power in your resistor and is probably a terrible idea. Check out the written tutorial on CircuitBread.com to see the calculations on how much power that resistor will have to dissipate.
Animation .put some animation , we want to see it's working. Put oscilloscope on the screen to show how voltage changes for different voltage and current , ac, dc. input to output
Thanks for the feedback! We've been discussing this and planning on doing more visually intensive (either with benchtop tools or animations) presentations.
The scene from Braveheart where Mel Gibson is holding back the warriors before attack. This is what I imagine is actually happening in a Zener diode. There's a little speck of Mel in there.
We have two more tutorials that show these in circuits: www.circuitbread.com/tutorials/zener-diode-as-voltage-regulator-conceptual-overview www.circuitbread.com/tutorials/practical-example-of-zener-diode-as-a-voltage-regulator Hopefully those help!
good points but no one wants to see teacher while learning instead they want to see the practical, diagrams, schematic etc for every point being said else its waste of time.
