Looking to design/ build a pair of H Bridges

Looking at the maximum rating on the drain, 72A peak, 18A continuous I should be fine right?

Those ratings are typically for pulsed current (5us for example) into a resistive load, and with the case at 25c.

So I typically derate them 50% for my applications. For 15amp current, I use a 30amp (continuous) mosfet.
