I am simulating circuits on SPICE (LTSpice and PSpice), I have assigned tolerances to both resistors, capacitors and inductors.
But now I would like to try to understand how much a transistor can deviate from its parameters.
Assuming to use the pair of transistors 2N5551 and 2N5401, I would like to understand what is the percentage of possible variation of all the SPICE parameters, not just the beta. In this way I would be able to reduce errors and predict the behavior of circuits in montecarlo simulations.
