Diode I/V comparison graph
« on: October 23, 2020, 12:50:50 PM »


You guys have seen this?
Little detail : BS170 body diode almost exactly the same as 1N4148, 2N7000 body diode steeper!

that's how you can hack a diode as a variable resistor, in a really quick and dirty kind of way, say for an active filter
"...and weird on top!"

Too bad this doesn't go down another couple decades, or give the reverse of the zener. Very cool data.

nice graph, i wish i had it soner

only downside that its sometimes hard to see which diode goes with which colour, like the IRL510 and the LED R rectangular are kind of the same colour.

very much thanks,

It took me a bit to figure out the scheme, but I believe the diodes are sorted by where their line starts at zero current, and then listed from left to right at the bottom.

Nice work, Steben!

Its not my work, I stumbled on it and thought it would be a crime not to share.
