Email Required, but never shown. I am working in Delhi. On page 2 of the data sheet it says Vgsth is -2V min and -4V max.

IRF9540N MOSFET. Datasheet pdf. Equivalent

Saturation voltage of a bipolar transistor can be less or much less than the Vbe drop. BCxx has a typical saturation voltage irg9540n about 0.

I would recommend against switching the ground side on complex components like a WiFi module. Is that the maximum and is that certain? Thank you for the link.

All the circuit samples in the data sheet use 10V as the gate voltage. A FET becomes attractive: I iirf9540n need around mA for my WiFi.

However, the graphs are for typical values. A normal transistor would do and i experimented too. I am able to get it in bangalore and mumbai but they are taking long time for shipping say weeks. For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn. Sign up or log in Sign up using Google. Lower values of R4 may be needed to get low enoughy saturation voltage. It’s best to give components like that a solid connection to the ground plane without any pinch points.

Q2 can be a single adequately rated PNP or several smaller ones in parallel. Your circuit seems correct in principle.

Post as a guest Name. Also make sure you are using a static wrist strap and anti static bags. You are right, using krf9540n i got 1.

Lower beta transistors can be used with smaller values of R4. 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. This affects what is best to use. I tried using darlington pair but the voltage drop is around 1.

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. Home Questions Tags Users Unanswered. Sign up using Email and Password.

They are much more common, cheaper and usually have a lower on resistance than p-channel for the price. Mosfets are incredibly dqtasheet to static and I have destroyed many like this. But the voltage drop is around 0. A VERY undemanding spec.

You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth. This would not be good.

Yes i am connecting the gate to the ground so that i get Sign up using Facebook. Do you want some specific parts recommended or is the above good enough? A wide range of small bipolar PNPs will work. R4 then not needed but does no harm.

Thank you for understanding my problem. Instead of switching 3.

Why is my WiFi chip not powering up? The problem is the WiFi module is designed such that i have given provision to switch datazheet 3.

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. The only problems are: So now the Vgs is The connection is as follows Source 3. The IRFN is unsuitable for the task.
