An ordinary bipolar transistor has three leads so the first digit for it will be 2. 2 pnp 2n3906. Transistor Count Wikipedia What Do Transistor S Podcast Stats Look Like Transistor Simple 12v Transistor Switching Power Supply Elec Circuit The gain is often quoted at a particular collector current ic which is usually in the middle of the transistors range for example 100 at 20ma means the gain is at least 100 at 20ma.
