Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research?

There are many Gnd pins in Datashewt chip and they are all connected so i have no option of disconnecting all the ground pins to make a low side switch.

Your circuit seems correct in principle. BCxx has a typical saturation voltage of about 0. This would not be good. Do you have datasheef access to a range of parts? Your available Vgs max is R3 is ‘or safety’ to ensure Q2 turns off.

BCxx7 data sheet here Vatasheet Fig 9. Russell McMahon k 9 Mosfets are incredibly sensitive to static and I have destroyed many like this. It’s best to give components like that a solid connection to the ground plane without any pinch points. R2 not required if input is always driven high or low and never floats.

A wide range of small bipolar PNPs will work. This affects what is best to use. A normal transistor would do and i experimented too. My load current may vary from 0 to mA. So a Darlington may not do what you want but a single bipolar may. Here is one that seems will work with 3V sparkfun.

Thank you for the link. To do that with eg 0. So now the Vgs is 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. 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.

Although they usually seem to fail on rather than off. Yes i am connecting the gate to the ground so that i get Vbe can be say 0. I may need around mA for my WiFi. A FET becomes attractive: I am working in Delhi. You mention mA WiFi current.

Thank you for understanding my problem. They are much more common, cheaper and usually have a lower on resistance than p-channel for the price.

I have to go with high side switch only. Lower beta transistors can be used with smaller values of R4. The connection is as follows Source 3.

Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth.

While figs 1 and 2 suggest the 3. R4 then not needed but does no harm. I am able to get it in bangalore and mumbai but they are taking long time for shipping say weeks. The part has a beta of typical range.

Q2 can be datashedt single adequately rated PNP or several smaller ones in parallel. Also make sure you are using a static wrist strap and anti static bags.

I have no idea what could be the issue? Normal transistors BC is switching only mA.

All the circuit samples in the data sheet use 10V as the gate voltage.
