WebJan 22, 2014 · Normally, the gate of JFET is like a reverse-biased diode (which is why little current flows into the base). If the gate voltage on a JFET is out of range, the junction can become forward-biased, and then a lot of current flows (which can develop a voltage via the 500 ohm base resistor). You generally want to avoid this situation.
