Screwed up pfet SOT-23 design. Swapped Source and Drain
(1/1)
Ribster:
Hey everybody.
So what the title describes. I've swapped pin 2 and 3 of a SOT-23 pFET.
Respinning my boards would be a bit of a shame and wastefull.
I'm looking at some P MOSFETs that are like this: 1- GATE, 2 - DRAIN, 3 - SOURCE.
I've really screwed the pooch, since i now see that every one of them is DRAIN on pin 3... :palm:
Suggestions ?

If you have just a few, turn over the part and bend the leads down. It'll be cocked at an angle.
An N-FET wouldn't short out the path, but you'd have to figure out some way to invert (and most likely boost) the gate voltage, which will be a tall order in most circuits.

Depends on how your pads are arranged/shaped, a different package (SC-70 for example) might fit as is.

I did just that and my design works as intended.
I just made 12 boards, and i want them to be ready for a client.

Thanks! I’ll have a look for SC-70 pinouts
