5v triggering voltage
All transistors are switched on fully when there is 0.7V applied to the base. There is no such thing as a 5V triggering transistor.
and can supply up to 12 volts,no more.
Transistors do not supply voltage. They can only switch current. You have to supply the voltage and the transistor can in effect switch it on and off. Most simple transistors can switch voltages UP TO 60V. That means they can also switch lower voltages if you supply them.
Tried to read some datasheets and get to shit bricks
