Bc 547 should be in your spare box so buy a dozen even if it’s not the best fit now.
I don’t remember Mosfet codes but you may want one. However this is for many milli amps, I’m concerned on things catching fire without proper ventilation. A quick search gave me IRF540N. It’s the TO-20 package that gives the hint of operating power, that metal back is for screwing a heat sink. Watch your fingers when it works properly.
