Re: Digital transistors
Thanks very much, Bill.
I'll have a read of that a little later when I get some spare time. Cheers Richard. |

Re: Transistor information required please.
That would be a suspiciously low number, so a big red flag to keep on searching. In this case it's DTC144, with the suffix indicating the resistor values. A normal NPN can be used, adding those resistors.
