These are "forgotten" transistors that you don't see that often. But are they really obsolete? What Advantages and disadvantages do they come with?? And do the newest SiC JFETs make a difference?? Let's find out! ;-) Thanks to Mouser Electronics for sponsoring this video 0:00 Forgotten Transistor?? 1:06 Intro 1:42 JFETs are like MOSFETs (Fail) 3:26 How to drive a JFET (Theory) 4:35 Practical Ways to drive JFET 6:28 Big Disadvantage of JFET 6:55 Advantages of JFET 7:26 JFET as an Amplifier (Audio) 8:06 JFET as Constant Current Sink 8:43 JFET as Variable Resistor 9:11 SiC JFET & Verdict
