You were told Is and you now know IL. You should be able to calculate the combined current of Iz and Ic.I'd found the VRL and IL, and the question need me to find the Iz and Ic, this two current i have no idea how to start
Look in the data sheet "Electrical Characteristics" table for the Hfe value at the collector current closest to the current in your circuit. Generally you want to use the minimum Hfe value column which gives you the worst-case maximum base current.But in your opinion, what is the easier way to find beta from the datasheet ?
Thanks again, i will try itLook in the data sheet "Electrical Characteristics" table for the Hfe value at the collector current closest to the current in your circuit. Generally you want to use the minimum Hfe value column which gives you the worst-case maximum base current.
The collector current is ~50 ma. Follow the vertical line upwards from 50 mA on the x-axis. Find the point where it intersects the 25°C curve and read across to the left on the y-axis. It looks like ~200 to me. If you expect the transistor to get hotter or colder, then use the other temperature curves.Thank you very much.
