Why are there more N type than P type MOSFETs?

+5
−0

I was looking at different transistors, especially MOSFETS and I saw that N type MOSFETs seem to be way more popular to be used in circuit design. Is there a reason for that, or am I mistaken?

One reason could be that N type MOSFET can switch loads that are in Drain, meaning that whatever the load voltage, you can turn it on/off directly with any microcontroller, provided that the MOSFET is 5V or 3.3V logic level. You could invert it and do the same with P-Channel, but N-Channel just feels more natural, since it shares common ground. Furthermore, going into design details, N-Channel MOSFETS have faster switching due to higher electron-hole mobility. Due to this, P-Channel MOSFETS have a higher resistance when fully on.

Presumably these characteristics lead to N-Channel being more common.

@Olin. After your action, who would want to leave any comment after downvoting? You create a Meta to make downvotes public, and at the same time act with an unmatched virulence against a person who has duly justified his downvote. You have used incorrectly the upvoting mechanism to fight my downvote, which is conceivable for posts that are savagely downvoted, but certainly not in these conditions. I guess I'm not the only person who knows who has used multiple avatars to upvote himself from the beginning and polluted this site with downvotes for his crusade. I should add I have some sympathy for this not very young, somewhat narcissist person, and I would not totally disagree with him, if only he had done it courageously and not in this disgusting way. It was the end of the day and I had good reasons to be bitter. My compliments Mr Olin, you are really encouraging downvotes to be public.
