A shiny new dime to the one that identifies this FET
« on: July 08, 2024, 02:24:48 am »
Picked up a non-working high end 32" Acer gaming monitor. Was hoping it was just a bad cap on the power board but not so lucky this time. Anyway, I think I found the problem. This SMD FET, and I know at least it is a FET cuz the pins are marked G, D, and S. This FET sends greater than 1.8V to turn on a pair of LED controller IC's, no voltage present. This FET is on the main board. Power board, I believe is good, puts out 19v which gets converted to 12v out to the main board and 28v for the leds. Looked all over the interweb for this daggum FET but can not find it. 15F46 is how its marked.

This thread may provide a clue:

https://www.reddit.com/r/AskElectronics/comments/o7f4dh/unable_to_identify_this_blown_transistor_on_an/

There is a similarly marked MOSFET with a long underline. Its marking code is 12YWW.

Based on that info, I found this:

P3202CMG, NIKO-SEM, N-channel FET, 20V, 5A, 32mOhm, marking 15yww, SOT23:

Wow, that was some brilliant detective work! I found an Infineon Technologies IRLML6244TRPBF that is rated a little higher amperage that I think will do the trick!
