Cool MOSFET Type

Several years ago GM, Tekin and others started using a Surface Mount type transistor (V-FET was one such name) that was much smaller, lighter and more efficient than previous offerings. I don't know if there are any FET's that are newer than those. I know M.Troniks uses something called a Gen-R-Fet and Novak uses a TO262 in their GT7. These may be the same thing everybody uses, just named differently. Over the past 4-5 years the emphasis has been on small, lightweight and feature packed speedos. They may be more efficient and pack in a few more features, but I don't think they can hold up to the stress of high current applications nearly as well as the older Tekin and Novak speedos. Hope this answers a few questions!

An electronician at our club, have replaced the FET's in an LRP Sprinter - now it handles 6 turns motors without any trouble.

Unfortunately, he's left the club, so I cant help with much details. However, I do remember that the FET's were in TO-220 cases and that they had very small raise time (dont sure it's the right name, but they were extremely fast switching on-of-on-of). I remember he told that that was one of the most critical parameters.

By the way: These FET's were relative cheap - something like 5-10$ each.

Just out of interest are these smaller MOSFETS more durable than the larger style MOSFTEs?
