Re: Lbss139lt1g
This is a low power, casual switch so pretty much any n-channel mosfet should do.
However you should confirm it is the problem by pulling it out, shorting the gate to source with tweezers and then testing the mosfet again. -
Re: Lbss139lt1g
It absolutely can be fixed. It'll require skillz, a dremel, a microscope and UV mask & light but it can be fixed.Comment

Hello everyone.
Someone brought this poor hp in.
All power rails had normal resistances so i turned it on. Instant power cutoff...
First mosfet was shorted so replaced it...
After that I have tryed to start since no short was on the main power rail. the CPU middle dual mosfet heated up and protection shut down the laptop.
After investigating i have found that when the mosftet turning on then the mostfet got instantly hot (not the CPU)
Removed the faulty mosfet. -> now laptop turns on CPU mildly gets hot but laptop gives the common 5 long 3 short LED... -

Hellow guys,
I am trying to replace an AON7403 Mosfet but i dot not have in my stock the same. So i wonder if there is any equivalent to this Mosfet.
Thank you very much. -
I tried to use this method:
Testing an N-channel MOSFET:
Step 1: Discharge the Gate (turn off the MOSFET)
Place the black probe (COM) on the Source (S) and the red probe on the Drain (D). The multimeter should show no continuity (high resistance or "OL" – open line).
Then, touch the black probe to the Source (S) and the red probe to the Gate (G). This discharges any stored charge in the Gate, turning the MOSFET off.
Step 2: Charge the Gate (turn on the MOSFET)
Now, place the red probe on the Gate (G) and the black probe on the...09-27-2024, 03:31 AM -
Hi,
I'm looking for an equivalent dule mosfet for (IR3598MTRPBF - Dual MOSFET Driver, High Side, and Low Side, 4.0V to 13.2V Drive voltage, 20 ns delay, QFN-16)
it's for motherboard ram voltage.
I hope someone can help me.
Thank you.
