JFETs are single junction devices that have some tricks up there sleeves …

My main project is still going through a hiatus, so to kill the time and because I might have some use for them down the line, let’s talk about JFETs (Junction Field Effect Transistors).

We start by comparing MOSFETs, BJTs, SCRs and TRIACS with JFETs. Then we have a look at their working principle. At the end we go through the datasheet of a J176 JFET.

00:00 Intro – let’s have a look at JFETs
00:33 JFETs are different – comparison
04:56 Working principle – just a junction
12:11 Datasheet – J176 as an example
24:17 Wrap-up – part 2 coming up, but maybe not next week, bye
