Data Sheet help: Current flowing through a MOSFET module

Question

In a MOSFET module, when looking at the data sheet can I assume the current through each MOSFET device is the given Id, or is Id the current moving through the entire MOSFET module?

For the data sheet attached I'm assuming the current through each MOSFET is 265 A and through the module is 530 A? Or is 530A going through each MOSFET under maximum operation?

Single. Specs. Only. There may be a Pmax for entire package with sink. — Tony Stewart EE75, Jul 05 '21 at 13:05
As the package has a set of pins for each device, the specs are per device. This is confirmed by the note that the current limit is 30 A due to the press-fit pins. Bear in mind that's a maximum, not a recommended, operating current. — Neil_UK, Jul 05 '21 at 13:12

Yes. The specs are for an individual MOSFET in the module, not the module as a whole, unless explicitly stated otherwise.

Isn't 530A too high to be going though the MOSFET? I thought it would be – FromMyWindow Jul 06 '21 at 17:58
@FromMyWindow The manufacturer promises that under ideal conditions (the module somehow kept at 25 C) you can maintain a continous drain current as high as 719 A, and 541 A with the module at 90 C. In practice you want a healthy margin much lower than that. – jms Jul 06 '21 at 18:08
Thank you for your answer! (I'll assume that's the case with modules which are full bridge) – FromMyWindow Jul 06 '21 at 18:23
