| May 12, 2022 at 8:08 | comment | added | A.H.Z | @AndrewMorton I actually ended up using a metallic sheet with two holes for screws. I forcefully pushed those screws down the space between the laminations in the heatsink. As for the USB electronic loads I unfortunately did not find anything worth noting. I will check out the youtube video though. | |

| May 9, 2022 at 17:20 | comment | added | Andrew Morton | @A.H.Z Did you find anything useful in any reviews of USB electronic loads? If the MOSFET is on a PCB, then you can use some nuts on those screws that are on the heatsink to attach the heatsink to the PCB with the MOSFET in between. It might be a good idea to use something like large diameter washers under the nuts to spread the load on the PCB. (I haven't actually tried it myself, otherwise I could confidently write that as an answer.) | |

| May 3, 2022 at 12:02 | comment | added | rdtsc | If it were my experiment, I'd just clamp it; the more pressure, the better. But that datasheet is notably lacking in chart data - kind-of hard to gauge the device Safe Operating Area without it. | |
