Well, our teacher said us to pick one PNP bjt and plot the Ic(Vce) curve!
But I can use 2N2907...
But I can use 2N2907...
When plotting Ic(Vce) for 2N3055, the Early Voltage is 0????
hi Psy,As you can see at my #36 post, the values from directive .MEASURE gives me a slope of zero.
And yes, I'm using Y = mX + b
What you mean "have limitations"???hi Psy,
Why have we jumped back to post #36 for the 2N3055.???
It gives an apparent slope of zero because the Ib increments are to large.
Ref the 2N2907 look at this sim plot, what do you think the Early Voltage is now.??
EDIT:
Re-Checked the #36 asc, I suspect that the LTS 2N3055 Model has limitations.??
I suspect that the 2N3055 model is not detailed enough to calculate the small changes in Ic for small changes in Ib ie: the resolution of the model is too coarse.?What you mean "have limitations"???
The 2N3055H should already be part of your transistor library, let me know if you cannot find it.Thanks for the help... I'm going to replace my simulations with that one and recalculate Early Voltage!
Can you provide full model for 2N3055H so that i can add it to LTSpice?
Transistors don't have the same Early Volt. So I don't understand your question. 2N3055 is a high power transistor, and this is why it has different properties then 2N2222.ericgibbs, what can we say about 2N3055H regarding the big difference of Early Volt comparing with 2N2222??? Is it because of different Ic? What makes the Early Volt to change?
hi,Can you help me to explain why does this BJT has it's curves upside down?
