### Should I design with “N” parts or newer parts?

I noticed there are parts with "N" in the part name, for example the 1N4148 diode and the 2N2222 transistor, etc. What is the history of these parts? Where did they come from and why do they have ...

### AC DC Analysis of diode

in the following circuit: Im looking to find what $v_D(t)$ is given $V_γ = 0.7 V$ and $r_f = 0$. Now when doing the DC analysis, find that $VDQ = 0.7 V.$ But im having trouble finding ...

### Diodes in parallel

I need to protect about 5A @ 6V from something stupid like my revering the battery wires when connecting them to the circuit. I thought that I could use 5x 1A diodes in parallel, but it seems that I ...

### diode fails open

the question is asking this: the correct answers are as follows, Vlimit = 0 V, Vdiode = 5 V I don't get why it ended up like that. My intuition says that, "fails to open" means not functioning, ...
