[sdiy] What's this component?

[Ken Stone]

The part would be a custom numbering job for Power-One. It is most likely
something like a 2N3055 or 2N2955. Occasionally a darlington may be used,
but generally, it's a common power transistor. Yes, I know you said to-220.
That is why I said "something like".
