tussi said:Hi. Can anyone explain to me how to use a npn/pnp transistor(or where I can find some info), and what to look for in the datasheet?? I am a bit confused..
tussi said:Thanks for replying to my question. I have read the document, but I cant figure out the base voltage and current min/max for the active area and where the transistor is saturated. I have a datasheet from a 2n2222, can anyone help me locate this in the datsheet??
tussi said:Hi. Thanks for all help so far.. But I still don't understand this...
Can I put any cind of voltage levels into to the base, and just controll it with the current?? I am a bit confused... There shuld be 0,7 v over base --> emitter...??? Do I need a voltage over 0.7v to "start" the transistor????? This was not easy..
In the datasheet i found:
V(BR) EBO Emittter-base Breakdown
Voltage (IC = 0) IE = 10 mA 5V
VBE (s at )* Base-emitter Saturation
Voltage
IC = 150 mA IB = 15 mA 1.3V
IC = 500 mA IB = 50 mA 2.6V
Are this the maximum voltage input?
I have never worked with npn/pnp just fet's and there i must have a specific voltage level into the gate.
I want to learn how to amplify ac signals and dc levels. I use a fet as switch so it's the active area i am interresting in.
