Surface mount MOSFET question.

Greetings!

I'm trying to figure out how high loads I can put on a specific MOSFET without it overheating, but I can't really understand the datasheet...
(Blushes... and I'm supposed to be a nerd... )

Here's the datasheet:
www.elfa.se/pdf/71/07115538.pdf

It's a 'two in one' type SO8 Surface mount package which would be REALLY useful in a little project I'm working on.
It will be used to control two motors(only one way), with PWM, drawing a max of about 1A each.

Max 'working time' will be no more than 15 minutes, at the most, usually less than 10.

I'll be using a setup similar to the schematics posted in this thread:

Any advice on the Amperage rating on the diode?

Edit: Fixed typo...

    Looks like 2.5A is continuous on FR4 board and the higher current specs are limited by 10sec for 5.3 A and the other notes on page 2 that apply to pulsed current for 26A. Where I get lost is if the ratings apply for both channels or for each channel.

    Think Inside the box first and if that doesn't work..
    Re-arrange what's inside the box then...
    Think outside the BOX!
