im working on a arcade game board . the tip 120 for an eject soleniod is driven right off the processor leg, no pre -driver transistor. didnt even think that was possible, maybe that why it blew. is there a mosfet i can replace the tip120 with?

thanks

Why not just buy the tip 120 ? They are only from about
$ .50 to $ .75 from several big dealers.

Even ebay has what you want for less than $ 6 for 5 of
them including shipping. The larges cost is the $ 4 for
shipping That the arcade game machine is mentione in.
