The most important features of the Protect+ is the ability to carry a high amount of current, ideally in the range of 30 to 40 A continuously.

To do this, I used 3 MOSFETs in parallel for the high-side blocking and reverse blocking FETs, each with about 2.1-2.5 mOhm of on-resistance.

The PCB used is 4-layers, with 2 Oz outer and 1 Oz inner.

Shown below is a snapshot of the results obtained testing at 30 V, 29.5 A after about 5 minutes of continuous operation.
