This is the driver i want to use for my M-type M140 diode(link bellow). my question is do i need a heatsink? since i know i gotr the 1.5A version and it may have overheated or possibly from physical damage. But thats beside the point. Does this driver need a heatsink?? Thanks a lot for any help!

Note: Its set to 1.8A

Driver:

Survival Laser Driver

If you want to add information to a question you have posted, you should add it to your first post rather than starting a new thread an hour later asking the same question. Now you have two threads you need to keep track of which may have different pieces of information that may be of value to you.

Hi,
Yes heat sink the IC and you don't need a lot of thermal adhesive going out all over , nice and clean . M140+ 1.8A driver =heat sink.. Good luck with your build Pal..

Hi,
PI doesn't recommend it but i heat sink 1.8A and over. PI is correct though you don't really need to but thats just what i do and some don't . Its a personal choice thats all.

I basically heat-sink everything now whether I need to or not. I evendors add a little sink on the fasttech 532nm modules I get. It can only be a good thing unless you short something out or make it too big to fit into a module
