3N187, where to find this type of MOSFET in LTSpice

[michael1978]

hello 3N187, where to find this type of mosfet in ltspice, , because i am reading one good book and i need this 3N187, any help is welcome

How about this one?

You can search for equivalent components via Google.

is that with money?

is possible something similar to make self, me i don't know, only if somebody help me

You must buy transistor components. They would be impossible for a hobbyist to manufacture to spec.

i just need one dual gate, gratis, i find one, but i don't know how to install in ltspcie

than you, i will try to make

than you, i will try to make

no i don't know is dual gate model

 

[davenn]

no i don't know is dual gate model

that doesn't make sense

You should be able to model it as two stacked single gate fets. That's really all it is inside, sharing one channel so the drain of the lower one is also the source of the upper one. Set Vthresh for the upper one equal to the difference between the external lower and upper gate thresholds.

What is that “one good book” ?

Michael1978 also posted on the "All About Circuits" website. A solution was provided by Bordodynov who is also a stalwart of the Ltspice yahoo group. It is well worth joining the yahoo group if you are using Ltspice.

A text library file is attached for those who are interested in dual gate FET Ltspice models.
