MOS管型号CJ8820，10V驱动时，导通电阻只有21mΩ，

用5V驱动，导通电阻也只有24mΩ。

在SOT23封装中，还有比这个导通电阻更小的吗？

而且驱动电阻只有1.8V情况下，还可以导通啊。

You should claim it is N-MOS.

Since P-MOS cannot match the low on resistor as the N-MOS due to different manufacturing process.

So far, the best P-MOS I found is the NXP "PMV65XP,215"

"P沟道,-20V,-4.3A,74mΩ@-4.5V"

Any one knows a better P-MOS better than the NXP one?
