# Does LTSPICE automatically include avalanche parameters in its power dissipation measurements?

Does LTSPICE power calculation window like this

take into consideration MOSFET avalanche parameters and include them into the overall average power value?

That particular image is for a resistor not MOSFET.

• Power is just I * V. Do you see the avalanche effect in the current waveform? – The Photon Aug 22 '18 at 5:12

Another thing to keep in mind is LT spice has variable and fixed solvers, the variable time step solvers are mostly good at simulating high resolution\frequency simulations but sometimes have difficulty. Neither solver will simulate a time step beyond the maximum timestep specified in the .trans statement
