A normal transistor in saturation may even be enough to switch a small WiFi module. 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.

R3 is ‘or safety’ to ensure Q2 turns off. R4 then not needed but does no harm. I am working in Delhi.

Sign up using Email and Password. A VERY undemanding spec. For instance if in eg Mumbai or Bangalore there are many suppliers. Lower values of R4 may be needed to get low enoughy saturation voltage. Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. I have no idea what could be the issue?

So a Darlington may not do what you want but a single bipolar may. Home Questions Tags Users Unanswered.

Also make sure you are using a static wrist strap and anti static bags. But the voltage drop is around 0. The IRFN is unsuitable for the task.

The part has a beta of typical range. Do you have easy access to a range of parts?

This would not be good. Thank you for the dataaheet.

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. The only problems are: I am able to get it in bangalore and mumbai but they are taking long time for shipping say weeks. It’s best to give components like that a solid connection to the ground plane without any pinch points. If you look at graph in the datasheet of current vs gate-source voltage Fig 3 and extrapolate down to 3V you will see that almost no current will flow.

They are much more common, cheaper and usually have a lower on resistance than p-channel for the price. To do that with eg 0. Lower beta transistors can be used with smaller values of R4.

BCxx has a typical saturation voltage of about 0. You mention mA WiFi current. Here is one that seems will work with 3V sparkfun. Best likelihood, based on all evidence and the data sheet, is that even though your load current needed is tiny – the Vgsth value is so far above your drive voltage that it just sits and grins at you.

I would recommend against switching the ground side on complex components like a WiFi module.

Any help would ifr9540n appreciated. Thank you for understanding my problem. Normal transistors BC is switching only mA. Is that the maximum and is that certain?
