Hi Edward,

The Rdson is independent of the current. Temperature is the main factor.

Hi Donovan,

Thank you for your reply.

One more question, is there any way could reduce the Rdson?

Thank you.

Hi,

I believe the only way to reduce Rdson is to operate this device at temperatures below 25C. Rdson will decrease as temperature decreases. I hope this helps :-)
