I've made a device that has 20 circuits. (one of them is in attach)
The circuit in fig1 is used to switch on-off 10A DC, but when the circuit worked for 4-5 hours, some of the mosfets (2sk3569) burn.(1-2 percent of mosfets)
I use a heat sink for each 2 mosfets same as fig2.
Now I don't know what should I do?:bang:
I thank you in advance for your help.
Best regards:-D
