Your circuit seems correct in principle. The falling poutput voltage “steals” drive from the input so Vc2 out can never be less than 1 x Vbe or more.

A VERY undemanding spec. The IRFN is unsuitable for the task. I have no idea what could be the issue? My load current may vary from 0 to mA. Yes i am connecting the gate to the ground so that i get I would recommend against switching the ground side on complex components like a WiFi module.

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. Vijay Anand Chandrasekaran 45 1 What is irf99540n load current?

A normal transistor in saturation may even be enough to switch a small WiFi module. R4 then not needed but does no harm.

R2 not required if input is always driven high or low and never floats. However, the graphs are for typical eatasheet. While figs 1 and 2 suggest the 3. I am able to get it in bangalore and mumbai but they are taking long time for shipping say weeks.

Also make sure you are using a static wrist strap and anti static bags. A FET becomes attractive: Lower beta transistors can be used with smaller values of R4. You may have misunderstood the parameter Vgsth To turn on Vs – Vg needs to be comfortably greater in magnitude than Vgsth.

For instance if in eg Mumbai or Bangalore there are many suppliers. R3 is ‘or safety’ to ensure Q2 turns off. All the circuit samples in the data sheet use 10V as the gate voltage. For low saturation voltage both Darlington pair and Sziklai pair are bad because they “steal their own drive” as they turn.

Home Questions Tags Users Unanswered. 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. A wide range of small bipolar PNPs will work. Mosfets are incredibly sensitive to static and I have destroyed many like irf9504n.

I have to go with high side switch only.

I tried using darlington pair but the voltage drop is around 1.
