Transistors Guide

[Plexi]

Hi there!
I would like to share this guide that I found time ago:


Very useful and practical for pins orientation, polarity and hfe.

But, there's a lot of transistors that isn't in the list.
Anyone have/found a more complete one?

That's a pretty good one. There are a few out there, can't recommend one that's better; what I do if I'm going to work with an 'unknown' one is just go get the data sheet before I start my project.

I have a big collection of data sheets, LOL.  I save each one, have folders for BJT, FET/MOSFET, OPAMPS, Regulators, diodes...it was more important back in the dial-up days, when you might not be able to get on AOL and needed the info, ha ha!

Uff... the "Genesis" of the internet...what a black memories...

This chart was on/from the Beavis Audio webpage. It's down now but you can get it from the Internet Archive: http://web.archive.org/web/20140209025412/http://www.beavisaudio.com/techpages/Transistor-Pinouts/index.htm

your list - missing is BS170 and BS250, BF245a/b/c, BC557/8/9, K30A (or 2SK30A). also the pesky BC639 and 640, BD140. and, if a BC transistor has an "L" suffix, like BC182L, the pinout changes. much of this list can be found in pedal work.

the BF244 and 2N3819 sometimes pop-up, and have a trick pin.

Plexi - all that is missing is the "click click....click...<dial tone>"    ha ha!

I just cranked that up and told my wife I got back on AOL - she came running upstairs to see
