I want to use IRLR024N logic MOSFET to switch on/off a Sim800L module. This module consume 2A for 500μs and then consume only 200mA. I supply this module with 4V. This MOSFET able to switch on this module if I connect its Gate to an Esp32 gpio with resistor?

    Should work, but I'd think twice before using a low-side switch for something like this. – Klas-Kenny Feb 06 '22 at 13:49
  • You are right. I wanted to buy P-channel logic level MOSFET, but unfortunately in my country not available now. – DJDB999 Feb 06 '22 at 14:17
  • In my case p mosfet is not a good solution I think. In off state the gate is 3,3 volt and the source is 4 volt. The Vgs=0.7 volt so will flow current because the Vgs is not 0V. – DJDB999 Feb 06 '22 at 14:40
  • That's easily solved with a second transistor. See here for example: https://electronics.stackexchange.com/questions/606733/why-use-both-a-bjt-and-a-mosfet-for-switching-a-subcircuit – Klas-Kenny Feb 06 '22 at 15:24
