Sho Posted April 21, 2023 Share Posted April 21, 2023 I would like to measure the depletion mode MOS FET curve trace. But I can't find bipolar mode for depletion mode MOS FET. Link to comment Share on other sites More sharing options...
0 attila Posted April 21, 2023 Share Posted April 21, 2023 Hi @Sho Under Options change the 'Emitter' from -5V to -1V and also reduce the Rate to minimize the effect of transients. Link to comment Share on other sites More sharing options...
0 Sho Posted April 21, 2023 Author Share Posted April 21, 2023 Thank you very much. I will try. attila 1 Link to comment Share on other sites More sharing options...
0 Sho Posted May 1, 2023 Author Share Posted May 1, 2023 I can set the Vgs from minus to plus. But my MOS FET device characteristic is no good. Thank you. I will try another MOS FET. Link to comment Share on other sites More sharing options...
0 attila Posted May 2, 2023 Share Posted May 2, 2023 Hi @Sho I'm getting this with IRF510 Sho 1 Link to comment Share on other sites More sharing options...
0 linear_guy Posted May 7, 2023 Share Posted May 7, 2023 Maybe Sho can give us a part number. The IRF150 is enhancement mode NCH FET, not depletion mode. Vgs needs to be -3V or more negative for drain current to go to zero. Link to comment Share on other sites More sharing options...
