A normal transistor would do and i experimented too. Is that the maximum and is that certain? Do you have easy access to a range of parts? Home Questions Tags Users Unanswered. Thank you for understanding my problem. Can you please suggest me some MOSFETs specific parts which are locally available or which people often use for their research?
Do you want some specific parts recommended or is the above good enough? I may datqsheet around mA for my WiFi. You are right, using darlington i got 1.
The connection is as follows Source 3. Your available Vgs max is Sign up using Facebook. Sign up or log in Sign up using Google. My load current may vary from 0 to mA. For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn.
But the voltage drop is around 0. This affects what is best to use. They are much more common, cheaper and usually fatasheet a lower on resistance than p-channel for the irr9540n. You mention mA WiFi current.
Post as a guest Name. Mosfets are incredibly sensitive to static and I have destroyed many like this. All the circuit samples in the data sheet use 10V as the gate voltage. I have to go with high side switch only.

BCxx7 data sheet here See Fig 9. BCxx has a typical saturation voltage of about 0. Vijay Anand Chandrasekaran 45 1 Thank you for the link. Why is my WiFi chip not powering up? 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.
To do that with eg 0. On page 2 of the data sheet it says Vgsth is -2V min and -4V max. However, the graphs are for typical values. Here is one that seems will work with 3V sparkfun.
Saturation voltage of a bipolar transistor can be less or much less than irf95540n Vbe drop. My WiFi chip works fine with 2. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth.
R4 then not needed but does no harm. Email Required, but never shown.

Normal transistors BC is switching only mA. 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. Lower values of R4 may be needed to get low enoughy saturation voltage. The part has a beta of typical range. It’s best to give components like that a solid connection to the ground plane without any pinch points.
