General part question - Mosfets

[geoscash1]

Hey guys,

This is probably a dumb question to some of you but I don't understand so need to ask.

I drew an image and attached so you can look at what I am asking.

What is the direction arrow for on these mosfets? I understand the diode
portion of the drain but do not understand the directional arrows on the source lines.

I have read and read and believe it is current flow or direction but am not understanding
because the pin out is the same with these 2 different mosfets.


I circled the arrows in red that I am questioning. I happen to have 30 of the RFD14N05L's
from some old projects from some years ago and want to use them if possible so I have been
researching and noticed the different arrow direction and just don't know the answer.

Assumed it is a type of reverse or inverted type of flow but want to know for sure.

The arrow is equivalent to the arrow used in a diode, and designates the PN junction between the channel and body of the MOSFET. In discrete MOSFETs, the body is always tied to the source. The cathode side (pointy end) of the arrow is the N-side, so the left-hand symbol is for an N-channel device and the right-hand symbol is for an N-body (or P-channel) device.

Thank you Carl, I really appreciate the reply, that's a great explanation and easy to understand...


Its much appreciated.....
