Doubt regarding dual channel MOSFET datasheet

I came across a dual channel MOSFET link for dual channel MOSFET

But I am confused about the drain current of 0.63A. Do they mean drain current of each channel is 0.63A or for both channels combined?

• This NTJD440 isn't a dual channel MOSFET, it is a dual N-channel MOSFET meaning 2 NMOSFETs in one package. – Bimpelrekkie Dec 11 '18 at 7:22

This NTJD440 is a dual N-channel MOSFET meaning 2 NMOSFETs in one package.

The listed ratings are for ONE MOSFET. It would be very confusing of the combined rating was listed. Also note how in the drawing there is no connection between the two devices:

that generally means you can treat them as if each is a separate device.

It is listed that the maximum $$\I_D\$$ is 0.63 A. Nowhere does it state that this is the combined current (it would/should state that as: $$\I_D = I_{D1} + I_{D2}\$$ or similar).

So the 0.63 A is per device.
