The NPN and PNP from most "complementary pairs" of power transistors aren't very well matched. A decent model will help get out major problems, assess stabillity, compare topologies, etc. There are too many other things about the circuit, the layout, and the components that are NOT modeled and have a huge impact on whether you can get to. I use simulators as a guideline - I never take the results as gospel. I have tried with their MJ2955 model and the one for the 2N3055H, but this doesn't seem well matched. They have 3 different models for the 3055 in sp3 format, one of them not correct, because it's for a darlington, a different beast, and they call it a 2N3055A. The models available on onsemi's site are rather old (2004), but they may be recent enough if nothing has changed further since. However I was trying to find an MJ2955 that could match it, and it seems nothing I have found so far is correct. That model works well and I have used it on quasi complementary amps with no problems. Using LTSpice, there is no 2955 in its parts database and I suspect the 2N3055 that comes in its database must be rather recent, but we don't know where it came from and what parts it corresponds to. I would like to find recent models for the fast types manufactured now. There has been so many variants of the 3055 and the other flavors of the 2955, it's hard to find models that match for both the npn and pnp.
“With the integration of MGM, we wanted to take advantage of the existing team to expand our business in ways that will greatly benefit our customers around the world,” Jen Salke, who heads up Amazon and MGM Studios, said in a prepared statement.I know this thread has been dead for more than 10 years, but I couldn't find decent models that work properly together. The unit will be led by Chris Ottinger, the head of distribution at MGM, who will continue to oversee distribution of MGM’s new releases and film franchises, such as the James Bond and Rocky series. Last year, the e-commerce-behemoth-turned-media-giant closed its acquisition of MGM - which houses more than 4,000 film titles and 17,000 TV episodes - for $8.5 billion.Īt launch, the new division will offer several series and films including “Coming 2 America” and “Borat Subsequent Moviefilm,” Amazon said.
The works will be licensed via a new unit called Amazon MGM Studios Distribution, which expands the number of titles currently offered by Hollywood studio MGM.
