[@atkelar]

That's a common problem with lectures... they seem to be too focussed on "the details of X" instead of - at least at first - list all the different basic things and then go into the details. We had a professor that took that to the max: one year worth of lectures about how to make steel from iron, instead of the planned "material and machining basics".

[@PlasmaChannel]

Lol those diode title screen inserts were magical. One item i've never quite understood are diodes rated above ionization point, or above 360 volts. Let alone how a 15kV diode works. When you get to that high of voltage, my understanding of how they withstand such pressure starts to get foggy.

[@frabert]

I think those are just many diodes in series

[@Ferraday]

HV Si diodes like 15kV are composed of dozens of series PN junctions, with under 1kV blocked per diode. As such, the forward voltage is much higher than an ordinary Si diode, like 10-50v per device. The individual diodes they’re comprised of are quite thick and have a much higher voltage drop than ordinary diodes (~1.5). The magnitude of this resistance varies with construction as a standard or ultrafast device (like a 60hz xray tank/microwave oven diode vs high frequency voltage multiplier diodes), but either way they exhibit a great shift in forward voltage (which is seen very obviously due to being multiplied by the number of series voltage drops) with current.

[@socmonki]

Well, he is an electrical engineer. He knows a LOT more than someone like me (a lowly electrician) when it comes to electronic circuits and the nitty gritty of how electricity works at a fundamental level. However, when it comes to conduit, wiring, and all that jazz I think I'd have the upper hand since that's what I do every day. I do have to be familiar with a lot of the same concepts because if I wasn't I would just be some schmuck putting black to black and white to white and not knowing how anything really works. Still, when it comes to testing a panel we installed in a switch house (where you have equipement costing 10's of thousands that controls hundreds of thousands of volts that power the grid) we do get nervous. You can do everything right and have a faulty relay that trips when it shouldn't and that will take your breath away! And of course you never want to see the magic smoke, because once it's let out then, well, she's dead, Jim. Yea...my job can be stressful, but also awesome, because I deal with the power grid every day and any little mistake that could bring a line down could cause a HUGE amount of money to go poof. Not to mention if you are outside working around 500Kv and you have induced voltage on the equipment you're working on. That's why we have grounds! All that sizzling can be kind of invigorating though! I think I'm going to get a subscription to Brilliant though. I really want to know more about the engineering side of things.

I learned about most of this stuff when getting my degree (some of which I actually remembered despite not having used it in over 10 years), but I didn't realize that the overall pattern to all of these different types of diodes was essentially selecting for specific traits that *all* diodes have and working out formulations that increase those effects while tempering others. It's a good analog to selective breeding minus the biological and evolutionary undertones.

[@johncoops6897]

Yes, however the selective breeding is significantly lessened in "back-to-back" applications.

[@deang5622]

Not so much selection but designed for specific traits. Selection implies they are manufactured and then selected for their required purpose and that isn't what happens.

And variants on the Schottky diode named Tunnel diodes (or Esaki diodes), when mounted in a resonant cavity can be low-power microwave oscillators or amplifiers, when biased correctly.

[@BardhAzizi]

do you have a book (book title) about this that you could share?

[@samfedorka5629]

You can get a tunnel diode with a heterojunction (or just a normal junction of very high doping). Both of these have normal (ohmic) contacts not Schottky. I thought that's how they were made nowadays but I checked and it seems that there are some schottky MIM tunnel diodes out there. And if you're going for RF/microwave diodes, why not also mention Gunn diodes (which is barely a diode, but also used for high frequency) and IMPATT diodes (Definitely a diode, but more like a zener/avalanche diode than anything else), Wide BG PIN diodes, etc. I think of all the diodes I mentioned, PIN are probably the most common that didn't make it into the video. You can just buy those normally and they're not even that expensive. Even PIN photodiodes are available. I think solar panels use PIN, though I'm not sure about that. For anyone reading this later, a PIN diode is the same as a normal diode, but it has a layer of insulator between the P and N. This increases the depletion region by the width of the insulating layer. Because of this, they have more capacitance and also much higher E field. Because of the E-field they can switch very fast. Since the depletion region is large, some photodiodes are PIN diodes, since optically generated electrons are swept through the depletion region and out the diode very effectively from the high field, and there's a larger depletion region for the photon to hit.

[@altuber99_athlete]

0:43 Side note: Inductors and capacitors are linear, but their voltage-current plot (characteristic curve) is not a straight line through the origin, though. For example, if they're used in circuits operating in sinusoidal steady-state _(i.e._ sinusoidal voltages and currents), then their characteristic curve is actually an _ellipse_ centered at the origin.

[@rfmerrill]

You are correct. "linear" does not refer to the voltage-current plot, it refers to their linearity in the algebra sense: If you sum or scale inputs you get summed and scaled outputs. The instantaneous voltage and current do not have a direct linear relationship. Instead, there is a linear relationship between the voltage and current *functions* in the Hilbert space.

[@MaryAnnNytowl]

I love how you explain these complicated subjects in a simple way, and while keeping it fun, too.

@@bgezal Can you get a 3.1 volt variation of the 78L05? No. Sometimes you just want a voltage reference and not a voltage regulator.

[@deang5622]

So you didn't have or you did have but didn't how to calculate the value for a series resistor for the zener when breakdown voltage is reached? Okkkkkk. Little bit of knowledge is a dangerous thing...

@@deang5622 The 05 in the name is there for a reason. The LM317 is also cheap ;)

i remember those takes u took for "the link for carlson an steve moulds video"... respect ur hard work sir... salute.... and the video was ammazing as usual :) the intro music fr diff diodes was a good idea ... it was great...

[@i_am_ironman3380]

Highly educational stuff.

Great video sirji😍👍

[@kimyuling1156]

thank you for your videos! Im taking a mod in semiconductor right now and its really hard to understand but thank you for your high-quality videos! It makes learning these electrical things more fun and engaging than ever!

I have a 20 volt 2 amps solar panel, charging a 13 volt 100 amp battery, what type of diode should I buy to keep the solar panel from getting zapped by the battery?

[@arnolddergamer9668]

U cant get zapped by 20 Volts lol but you should use a füll bridge rectifier!

[@empathicallyyours4937]

@@arnolddergamer9668 since you didn't understand me correctly, I can't believe your answer might be correct. 100smp battery, connected to a 2 amp 20 volt solar panel for keeping it trickle charger, So my question is what's the kind of a diod I need for keeping the solar panel safe from the battery and not drain so much of the battery in milliamps as all diodes do rob some power. What's the efficient and correct diod for the task?

[@arnolddergamer9668]

Use a freewheling or flyback Diode (Just an high currant one or many in parallel)

[@scream_1live47]

Bro how do I understand this but not 5th grade math

[@Lam-s-Workshop]

This was the most entertaining and educative course about diodes I ever had. It was clearer than the several weeks my teacher tried to explain semiconductors in university

[@nkumshahi]

Mehdi please make this kind of video for all components. We got teacher who can't explain with this much clarity. 😊

[@hotlead554]

You need to make a video explaining vacuum valves , they sounds amazing.
