Hi All,

What is the consensus for a SMT replacement for the 2n3904?

I note the MMBT10 only has Vceo of 25 vs 40 for the 2n3n04.

I really do not want to tack leaded parts onto the board.

My latest ubitx is only getting 2w out on 15m, and i want to improve
the 45 Mhz transistors, and the tx drivers.

There are other versions of 2n2222 in SMT, DXT2222.

The MMBTh10 is better than the 3904 as is the SMT 2n2369 (mmbt2369) and BFR106.

As to voltage that spot (Q90)should not see more than maybe 16V ever.
