My starters pack just arrived and I'm doing some tests. I'm currently trying to create this circuit to test a transistor:
The manual of the transistor can be found here. The thing is that the manual does not say anything about b? How am I going to calculate Ib, Ic, and Ie?
The manual says that the transistor operates at 100mA max 200mA. So what I'm trying to do here is requiring that Ic = 100mA (just enough to operate) the voltage of the led according to the manual can operate at 2-3.6V and 20mA, so I require that Vl=3v (enough brightness) and now I somehow need to figure out R1, R2, R3.
The main problem right now is that I don't know b. Where can I find it? From class, the professor told us that b is a characteristic of the transistor so shouldn't be given by the manufacturer?
Thank you.
Mod: added datasheet for BC547
