Thread starter eblc Start date Nov 20, I figured out a way to make it work in multisim, although im not entirely sure how its working. I guess resistors are allowed too. I have quite a few of these in my part drawer and also got their datasheet. Starting with the gate drive. In practice, this circuit would destroy the jfet and LED2 For an N channel 2n, it is very rare dagasheet the gate ever becomes more positive than either of the other terminals because it is normal to have it reverse biased.

A typical jfet model is of the form: Search Forums Recent Posts. Each circuit should have a designated output connection. Can datasheeh explain how transistor switching of that small current is able to drive the LEDs? What else is allowed? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at datasjeet If you cannot see it, paste this into the standard.
Sep 16, 4. You know that an N-channel JFET needs a negative voltage on the gate relative to the source to turn it OFF, and it will be ON by default when the gate voltage is equal to the source voltage. Datasheet pdf. Equivalent Perhaps someone else will have an idea of datahseet expected and will post some hints for you. Just saying hello Started by MichaelaJoy Yesterday at 6: Then you would probably want a higher voltage rail for the drain circuit.
After that, you can post your question and 23n members will help you out. To participate you need to register. Here is a snippet from multisim. Thread starter eblc Start date Nov 20, When the transistor circuit is off, a red led should glow, when the transistor circuit datazheet on, a green led should glow.
In practice, this circuit would destroy the jfet and LED2 For an N channel jfet, it is very rare that the gate ever becomes more positive than either of the other terminals datawheet it is normal to have it reverse biased. I need a circuit using a ntype jfet so that when I close a switch, a green led lights indicating the transistor is on and then when i open the switch, the green led goes off and a red led comes on indicating the transistor is off. Can you send that model for me also?

I appreciate all your help. Forums New posts Search forums. N channel Fet v npn. Ask a Question Want to reply to this thread or ask your own question? Sep 16, 5. This is different from junction transistors and MOSFETs, both of which need a source of bias voltage at their control terminal before they will conduct. This would produce uneven brightness in the LEDs and would not be used in a practical circuit. The change you need to make is to apply a negative voltage to the gate, not a positive one.
That will do nicely. What is this circuit? Started by fastline Yesterday at 8: Last edited by a moderator: Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
But the datasheet for the 2N states the drain saturation current, I DSSis just a fraction of one milliamp. TOP 10 Related.
