Re: ao4409 mosfet equivalent
Was the old one shorted out? May be the drive circuit is not working.
Per AO, the sub is 4447, see the spreadsheet.Never stop learning

Re: ao4409 mosfet equivalent
Dear, 4409 and 4407 is P channel. So must work. for checking this put a wire for that connection. what is the size original one and replaced one. I have faced like this problem in HP one. same number but size is different. So gate is going low. So not working. Then Last I replaced with real size.Then worked. Please upload datasheet of laptop and faulty part numberComment

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. -
