| Dec 24, 2022 at 17:37 | comment | added | Jonathan S. | Have you considered using a different MOSFET, like the IRLB3036PBF for example? It costs $5 and has 10x lower on-resistance at only twice the gate charge. You'd only need a single one of them. MOSFET technology has come a long way since the IRLZ44N was introduced. | |

| Dec 24, 2022 at 17:31 | comment | added | Jonathan S. | Are you still using the IRLZ44N? What's your gate drive voltage? | |
