I received mine last week. The IRFP240's and IRFP9240's have little labels on them with four digit numbers such as 3974 or 3977. Is this the matching voltage, such as 3.974 or 3.977 volts, Vgs?

And now for another stupid question. Which company did International Rectifier "divest" these parts to and where is the best place to get a data sheet on the ones we have in this buy?

Tom

Hi Tom,

I'm pretty sure those are Vgs values.

As for datasheets, you can try datasheetcatalog.com:

Yes, that's Vgs in mV

Now they're Vishay's ( http://www.vishay.com/irf-products/ )

[Tarasque]

Back online!

I'm again online...I guess everyone have received the fets by now. I also received a lot of mail. I will reply in the next day's.

Yes...The little labels represent the Ugs in mV.

I hope to have a big batch of 2SK2221 AND 2SJ352 Hitatchi fet's soon😉

 

[jleaman]

I got mine, however Customs Canada opened mine to have a lookie lou. :>)

 

[Tarasque]

As I'm now looking at the cases of my F4, I would like to know from you guy's what heatsinking you are planning to use.

Any suggestion?

 

[Jaac]

look at the original thread of the F4 there are many pictures. I'm planning to use 2 sk56 200mm high for one stereo F4. for photo's see my photo album.

Hi Maurice !
Maybe just have a look at this ref 170135572805 on eBay.
Don't know how to calculate the size with Rth factor.
Hope someone could help us, I've bought a pair of heatsinks, the same as Traw.
A big THANK for your help !

 

[Tarasque]

I still have a couple of F4 sets available.

 

[Studley]

got mine

Many Thanks T.

F4 FETs

Hi Tarasque,

I would be also interested in a set of FETs for F4. Do you have any left?
