Guide to 2n series transistors approximate specs and characteristics. Here lets us assume the load here consumes around ma maximum so our collector current i c ma. They are designed for audio amplifiers and drivers utilizing complementary or quasicomplementary circuits. In our case for a collector current of ma we have to pass a base current of 16ma.
To make this current flow through the transistor the value of base current i b can be calculated using the transisttor formula as we know the transistor is a current controlled device meaning, we have pass some current i b thorough the base of the transistor to turn it on. However, stmicroelectronics assumes no responsib ility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use. However this vale will not be very accurate because the transistor will have an internal voltage drop across the collector current, so it mostly experimental to get the maximum current from the transistor.
