Suriken Full Member Posts: I am following this tutorial: With this mpsfet I can make my prototype work with a 40w lamp light lamp like a charm. But whenever I connect the heat lamp w it fails.
Arduino sends the right signal to the mosfet but this start smelling bad and can’t control it. Temperature starts to get higher and higher.
Replace for IRF
I think it is because the watts this mosfet can dissipate is 74w and w is higher. I would want to find one for w at least or w because I would want to connect a heater lamp bigger in near future.
Can you recommend me a mosfet similar to irf but with better dissipation? Maybe the problem is another one.
IRF830, SiHF830 product information
In that case, what would the solution be? OldSteve Faraday Member Posts: With 5V on the gate, the IRF won’t be switching right on, so the Rds on will be quite high, resulting in excessive power dissipation.
What voltage are you working with? Please do not PM modfet for help. I am not a personal consultant. And others will benefit as well if you post your question publicly on the forums.
I am using some arduino mini 3. For supplies I was thinking on ebay. I usually buy everything there. With the tutorial I wrote in my first post, 40w lamp works like a charm.
Suriken on Apr 18, I don’t know much about electronic.
Using IRF830 MOSFET as a switch in arduino project
I don’t know what you mean about the voltage I am switching. And this is the code: As a newcomer to electronics, I recommend that you forget it. And you won’t get it to work up to the power levels that you want anyway.
Circuits of this nature are best left to the professionals. So, even if I change the mosfet by another with better specs, I will keep having the same issues, don’t I? I will try to find another way to achieve this. It worked fine with a 40w lamp during a couple of weeks.
I have no idea what that is.

Can you point me to a one Moefet could use or a diagram the one I uploaded before? And really, newcomers to electronics shouldn’t be trying to build mains powered circuitry without the benefit of a nice, safe, step-down transformer.
