I’m trying to build a circuit to allow my Arduino to control power (switch) a 12V 500ma load. I’ve read a good tutorial at bildr High-Power Control: Arduino + N-Channel MOSFET - bildr which explains most of what I need.
It so happens that I have a stack of old VNP20N07 ICs that I found in my parts bin. The data sheet calls this a “Power MOSFET”. The tutorial says that I need an N-channel MOSFET, and recommends the RFP30N06LE.
From my research it sounds like the Power MOSFET is used more in audio amplification applications. But I couldn’t find anything in the datasheet to suggest that it wouldn’t just switch power like the regular N-channel MOSFET.
For my purposes, can I use the VNP20N in place of the RFP30N06LE? If not, why not?
