I've been doing my prototyping a high current circuit with 25ish amps using tht components. I recently ordered some smd versions of the same components to see the size they would be for a circuit board. I am stunned at how much smaller the smd version of a 200A mosfet is. I was able to solder some leads into it just because I couldnt believe it would handle the current the same way as the much larger THT component. To my surprise, after maybe an hour or so of keeping the large LED on, it didnt gain any more heat than the through hole mosfet.
I'm just struggling to understand how something a mere fraction of the size can handle it?
