Question: Can a Zener diode with a capacitor potentially simulate a few milliseconds delay? I'm trying to figure out a small circuit to create a very brief delay before closing a circuit, and so far it would require a 555 timer. I don't want to incorporate any ICs in this PCB - I want it to be as simple as possible.

So, I was thinking a Zener could assist with this. Charge a capacitor which feeds a negative current into a Zener diode's cathode. At one point, it would reach its breakdown point and allow negative current through. Then, using another diode(?), capture that negative current and close a solid state relay, thus closing the external circuit on a delay of a few milliseconds.

I have no idea how to actually design such a circuit (or much of any for that matter). I just suspect this might be possible. Any tips or possibly help in actually creating such a thing?

Hello,

I was recently searching for specific types of a Schottky Diode and/or Fuse for a 750 watt inverter. I would like to use both and I see in the info. on this tutorial, it is possible. Does the volts matter or does the watts matter when I am picking a diode to give me only "one-way" current?

P.S. Since I am dealing with 750 watts, I figured I would need a hefty sized fuse and diode. What do you think of these ideas?

Doesn't the an in anode imply anti which implies negative? Aren't anodes negative in other situations? How come the positive ones are called anodes in this case? Also, how come current is flowing into the positive end? Should positive charge be attracted to the negative end?
