2N7000 Pin Out??

Is this the correct pin out for a 2N7000...

My expectations, from bipolar's, would be, facing the flat, leads down. left-to-right...

Loading thread data ...

tried that magic new thingy called google?, if you type in the part number and possible the markings on the package it will most likely lead you to a datasheet where those who made it will tell you ;)

Yes, it is correct.

Yup, really is:

My expectations, from browsing many data sheets, is that the pinout of any three-terminal device is pretty well standardized:

Pin 1: random Pin 2: random Pin 3: random

So, maybe the 2N7000 is a little randomer than you thought -- it's still normal.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.

Even the pin numbers can be random. I've seen all possible permutations of 1-2-3 on various SOT23 parts. We use the "Motorola" convention, and force any parts that we use into it.

All you need is a ohmmeter to discover/verify the pinout.

Sno-o-o-ort! I'll measure for the body diode just to make sure ;-) ...Jim Thompson

Facing the curve and bottom (nothing sexual) , leads pointing 7'oc, labels left-to-right

2N2222: C-B-E (usually ground E) 2N7000: D-G-S (usually ground S)

So, it's consistent.

Oh?? For all parts i have seen in D-pak, the substrate, for obvious reasons, is the center lead and tab. That means...

Nope, I got heaps of these and only the package addendum gave correct pinout -- which I posted here a while back...

Because the 2N7000 as shown is not D-pak, but TO-92.

Gaasfets are nice, because the package is usually the source.

Now if it was in a D-pak, needed for dissipation purposes, that would be nice especially in grounded gate configuration..

What is all this garbage of D-pak WRT this part, when it seems that it NEVER was (and never will be) available in D-pak?? There are a goodly number of other feet / fetsies that are available in that shoe.

What I use is a Steinel continuity checker, it has a 12V keyfob battery & 2 LEDs. Stick the + probe on the drain and the - on source, usually stray charge will cause enough conduction to make the LED glow, breifly moving the - probe to gate discharges it then back to source and no light means good MOSFET, move the positive to the gate to charge it and it conducts again.

With unknown leadouts its relatively simple to identify the gate as there's no continuity to either other terminal either way round. Which way round the body diode is tells you half of what else you need to know.

That is an extremely good and reliable way to destroy the gate...

Look at the link. It was broken across two lines, because it wasn't posted properly, between

Even nicer grounded-source, which is the way they are usually used.

I've done a lot of playing with 2N7000s with floating gates.

ftp://jjlarkin.lmi.net/2N7000.jpg

There are all sorts of fun things you can do with a 2N7000, a battery, a resistor, and an LED. I've never managed to blow a gate, even using body charge to tweak the floating gate bias. They seem to be pretty tough. The gates seem to leak not very many electrons per second.

I've been meaning to test some various mosfets to gate-voltage destruction. I get the impression they can usually stand a lot more than the datasheets suggest.

Does a 2N7000 typically have a gate zener?
