I too have the same problem. Discoverd it last night after buying 100 mosfets. I purchased the rfd14n05l fet not awre that the pinout on the fet is different to the board.
I now have 48 boards with that are usless without modification. Frustrated.

Brett,

Where did you get the PN to order? I am trying to track down what is going on here as these are the ones I am going to be stocking in my online store.

The original MOSFET used was a STF20NF06 and here is the datasheet. The original MOSFET was plastic tab isolated.

an optional part is the Mouser, RFD14N05L, as part # 512-RFP14N05L and here is the Datasheet

Even though the part in the Wiki is RFDxxx and the link RFPxxx, they should interchange for most purposes as the pinouts are the same (G-D-S). The RFDxxx is in a smaller TO-251 case where the RFPxxx is a TO-220 case.

None of these parts is going to work without modifications on the board pictured in daytimer's post.

That is what I am looking for....I will get back with you on this. There is actually a third one listed in the Mouser BOM link. So give me a a bit to sort this out.

Hi,

I was contacted yesterday about this issue, I'll be home tonite and will check the files. If a mistake has been made, I'll replace any and all 1.2 V boards with a new board at my cost.

The production house lost a server and my V1.1 files were lost, so we quickly knocked up a V1.2 file and added a fuse as it had been requested by a few people.

I dont want anyone to be out of pocket if it was my mistake. as for the Wiki, I'll also check and update as over time there can be changes to parts availability that I am not always aware of.

Thanks for letting me know, and I'll look to get this fixed ASAP.

It doesn't get more straight forward than that!

(What a great bunch of folks)
