Hi amazing people. I'm planning to build an aeroponic watering system. So I have a DC 12V water pump (15L, 4.2bar) LightEU DC 12V pressure pump, pressure water pump liquid pump for marine, boats, yacht, caravan, camping, outdoor, garden. : Amazon.de: Automotive
I'm powering it from mains and using an AC adapter to 12V at 8A.
I want to automatically switch the power of the pump by using a MOSFET, and I want to just see if I am using the right MOSFET. I have been reading the MOSFET datasheet but I cannot successfully determine if I have the right MOSFET. Also, to makes things easier (hopefully), I've found a MOSFET module:
component number is FR120N. I found a datasheet:
So, I was a bit concerned using other MOSFET modules which advised to run use more than 5A of current.
THe FR120N markets its product as "100V 9.4A". I guess the mosfet and the mosfet modules can have different max current ratings. But, anyhow should I be looking at the continuous drain current on the data sheet? It is 13A. Also, do I need a heat sink?
