Today, from ignorance I have fallen head-first into the world of MOSFET transistors. In my scramble to find some information on the MOSFET I will be using as a switch (HEXFET actually), I learned that MOSFETs in general come in two modes, enhancement mode, or depletion mode.
When I tried to find out which mode the IRF3710 was, from the datasheet, I found that it does not say (or maybe I need glasses). At this point I started searching to find how to tell the difference between the two modes. After some time I gathered that the schematic symbols differ:
The difference being the highlighted part below.
Three separate lines means enhancement-mode (left) and one solid line means depletion mode (right).
So, my question: Is this the only way to tell which is which, or is there a quicker way to tell (by markings on the device maybe?). Also, are there symbols out there which use a different method to differentiate between them?
I am asking here for my own learning, but also for other people who might have the same experience as me. I did not find that much helpful info in my searching.
