Joe,
The 3113 is a very interesting device and has the possibility of some serious applications using current sense, but it is a little beyond what the Victor needs. In comparison with the IRL 3103 FET currently supplied with the 884 it can deliver 64 amps vs. 7 for the 3113. If they were able to handle the current the cost per unit is almost $2 higher than 3103 (single unit quantity) for an added cost per 884 of $24. Even though the 3113 has a pulsed peak current of 100 amps, that is under specific conditions. The internal temperature shutdown is sensed inside the package and shutsdown the circuit while it waits for the temp to cycle down. Since this is not an external control the individual units would be cycling on and off at different times dependent on internal temperature, leaving the remaining online units to share the higher load.
