Need help to find MOSFET

Hello, I own an Intel NUC mini PC. I tried to swap 2 mosfets in order try try make it work ( the NUC was not working and one of them was bad). From my mistake both mosfets are destroyed. Any idea of how I could find replacements. The names are 22033 or 22D33. I found a same NUC that has the 2305 name instead so I guess the names are random. The first was near ethernet chip and the second near the power button.

Could anyone help?

  • Slim possibility, you might be able to use an ohmmeter to determine the where component leads are connected.
  • If you draw a circuit from these measurements and we might be able to help.

How do you know they are (were) mosfets? from the numbers I'd have guessed they were voltage regulators.

I can try. This is some info, a guy who has these nuc, gave me.

root@proxmox# sensors
nct6776-isa-0a30
Adapter: ISA adapter
Vcore: 856.00 mV (min = +0.00 V, max = +1.74 V)
in1: 904.00 mV (min = +0.00 V, max = +0.00 V) ALARM
AVCC: 3.33 V (min = +2.98 V, max = +3.63 V)
+3.3V: 3.33 V (min = +2.98 V, max = +3.63 V)
in4: 1.06 V (min = +0.00 V, max = +0.00 V) ALARM
in5: 0.00 V (min = +0.00 V, max = +0.00 V)
in6: 256.00 mV (min = +0.00 V, max = +0.00 V) ALARM
3VSB: 3.30 V (min = +2.98 V, max = +3.63 V)
Vbat: 3.23 V (min = +2.70 V, max = +3.63 V

I thought they are mosfets. Maybe you are right. How I can tell?

It is the same problem. This is where I got the info. Intel NUC DC53427HYE 5 sec blink issue - Page 1

Hi, @fofondoum888
Welcome to the forum.

I resume the original blown components were blown beyond getting a part number.

Tom.. :smiley: :+1: :coffee: :australia:

Also a seller from AliExpress insisted meto buy this N channel MOSFET

This was the last photo I managed to take. Not great quality though

The chip name was 22D33 in my NUC. On the NUC I found on the web it was 2305. Different numbers of the same chip?

Should I set the multimeter to continuity and then measure from the point where the leg of the chip should be to the other end of the line where the next component is? Right?

  • That’s what I would do.
