You're killing me ! It's all in the F5 article - common Source, common Drain, common Gate topologies, explanations and drawings... Just remember that every FET with 2SJ prefix is a P-channel and every 2SK is a N-channel device. Few simple things more: - every N-ch device has its Drain more positive than the Source in order to work - N-ch depletion mode device (f.e. JFET, like 2sk170) will not conduct the current only if its Source is far more positive than its Gate - N-ch enhanced mode device (f.e. HEXFET, like IRF610) will conduct the current only if its Gate is more positive (few volts) than its Source -With P-ch devices everything is the opposite |
