Vijay Anand Chandrasekaran 45 1 This affects what is best to use. Lower values of R4 may be needed to get low enoughy saturation voltage.

BCxx has a typical saturation voltage of about 0. It’s best to give datasheet like that a solid connection to the ground plane without any pinch points. Are you doing that?

Normal transistors BC is switching only mA. Sign up or log in Sign up using Google. If you pick through a bin of these you MAY find some that work somewhat better than others and some that MAY work well enough for you – but maybe not, and this cannot be guaranteed.

Q2 can be irf9540h single adequately rated PNP or several smaller ones in parallel. So a Darlington may not do what you want but a single bipolar may. I would recommend against switching the ground side on complex components like a WiFi module.

Email Required, but never shown. The IRFN – data sheet here needs about Any help would be appreciated. They are much more common, cheaper and usually have a lower on resistance than datashete for the price. I have no idea what could be the issue? Do you have easy access to a range daatasheet parts?

For instance if in eg Mumbai or Bangalore there are many suppliers.

R3 is ‘or safety’ to ensure Q2 turns off. Here is one that seems will irr9540n with 3V sparkfun. There are many Gnd pins in WiFi chip and they are all connected so i have no option of disconnecting all the ground pins to make a low side switch.

Post as a guest Name. All the circuit samples in the data sheet use 10V as the gate voltage.

My load current may vary from 0 to mA. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. But the voltage drop is around 0. You are right, using darlington i got 1.

The connection eatasheet as follows Source 3. Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. Thank you for understanding my problem. For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn.

You mention mA WiFi current. However, the graphs are for typical values. A FET becomes attractive: The only problems are: I tried using darlington pair but the voltage drop is around 1.
