Use any medium-signal NPN; that is to say, not small signal like the infamous 2N2222 whic would be a POS in that application.


That's bull, even the PN2222A can handle 1A peak, and maintains a minimum HFE of 50 at 250mA with VCE,sat under 0.2V. It is a general purpose switching transistor, not small signal, and is competitive with the 2N4401 in most applications.
