Discussion in ‘ General Electronics Chat ‘ started by sjgallagher2Dec 24, Dec 24, 1. Feb 6, More specifically, I was wondering about the Vgs vs Id chart, and the value of Vgs over one full input cycle. Here’s what I’m getting at: If you’d like to follow along with the simulation results, the red trace is the current through the JFET, the blue trace is the input, the green trace is the output at the source, and the teal unfortunately close to the green color is the value of Vgs over the cycle.
Can a JFET Pass More Than Idss?
From the datasheet of the 2n, the Idss: So judging by the curves of the teal trace – the value of Vgs – I can tell that it really doesn’t want to go above around 0. This is the voltage I feel as though the JFET will still allow more current, and represents that “max current” as opposed to the “slightly less than max” Idss.
This would seem, then, to be showing some sort of saturation state where the JFET can pass as much current as necessary? The current obviously goes to over 21mA, far above Idss. I think what it comes down to is I don’t fully understand what happens when you make Vgs positive, and I’ve been missing that detail any time I’ve been reading about JFETs.
Could anyone help me understand this phenomenon? Dec 24, 2.

Feb 17, 4, 1, Your JFET is wrongly biased. Check gate current in simulation. And for normal operation this diode should be reverse biased.
So, not forward bias the JFET gates. Under normal operating conditions, the JFET gate must be negatively biased relative to the source. The JFET may burn out if the gate is positively biased. And yes, Idss is the maximum current for normal operation condition.
