Hello there. I have about 20 or 30 of these 8 pin SMT packages in a strip.
I no longer remember what I got them for – lol, some future project that I have forgotten about; maybe one of Paul’s projects that I stocked up and have forgotten?
The markings: “F PA2HN” then next line “FDS”. Third line is a date code.
I have search to no avail all my orders at places I order from. I search the internet for that part number and came up with squat.
Anyone have any ideas?
In my opinion it is an FAIRCHILD (now ONSEMI) IC that could contain 2 separate N-channel Mos-Fet’s. F stands for the company name (Fairchild) and PA2HN markings are irrelevant. What is however the most relevant is that is written below (under) FSD (IE: FSD 8984, FSD 8878, FSD… etc.) what you have assumed to be the date code is actually not. So again, the second line(FSD) + the third line (4 numbers) is what makes the IC naming. See example pictured attached below. All in all if it is what I predict to be (an FSD8984) here is the datasheet for it: https://www.onsemi.com/pdf/datasheet/fds8984-d.pdf
PS: just realized that within my post (above) I have made a little mistake: Wherever I wrote FSD I meant to write FDS but was “unable” to edit/correct my post after 4 minutes of writing it since the time is “UP” by then… 😊
