does multisim 12 handle transistors and mosfets

If I complain to Mouser, will/should they give me replacements? Why the N Mosfet works ok I the other configuration? How do I choose the two Mosfets for this tasks? So, basically, I want to work with Mosfets as logic gates but they just won't work with 5V as I intended. Now, if I do the same thing as I did for the N Mosfet, and change the load position in the circuit, the mosfet now conducts, but I only get 1.1V. Notice that I want to use the P Mosfet giving 12V in the gate to 'close it' so it 'passes' 5V but I'm not even in that phase, since I can't even make it work with 0V.Īs for the N Mosfet, I tested the behaviour in simulator, and it worked as I intended. If I use 12V instead it works as intended. Problem 2 - With the P Mosfet, if I give it 5V in the source and I give it 0V in gate, it won't 'open' or at least not fully, so I can't get 5V on the drain. I solved this issue by connecting the load directly to 5V and it's ground to the mosfet and that way it works as I intended.Īnyway I would like to ask why does this happen, and how the input voltage makes a difference, and which mosfet I could buy that would solve this problem. I don't know if this is acceptable for a simulator or if I should complaint about it. If I give it instead 12V, there is no longer a big drop, and it works like I intended.īefore I requested this particular component from an online seller, I tested in its simulator (MultiSIM BLUE) and even with a load of 1 Ohm, the voltage out is 4.78V. Simulate this circuit – Schematic created using CircuitLab Problem 1 - With N Mosfet, this layout won't work because there is a big drop in the mosfet, and the load gets something like 2.8V. I'm having trouble in finding the specs that make the components suitable for those specific tasks. (Device current draw in the order of few 100s of milliamps. I want to use a N Mosfet for switching a device from a microcontroller (5V current and 5V signal), and a P Mosfet for giving a signal to the same microcontroller (5V signal, 12V input).
