20N60C3 question

[mu2]

Hi,

Anyone know of a substitute for the Infineon 20N60C3, TO-247 case?
Their part number is SWP20N60C3. Tried to order a SWP24N60C3 from Digikey, but they sent the wrong part and I'm not sure they have any more.
Is this part a common fault?
I'm working on an SMPS from a Vizio L37HDTV and that part is checking slightly leaky with my Sencore transistor / fet tester. That is the only thing that seems bad on the board. All caps have good ESR and value.
The 12 V and 24 V supplies don't come up when the 3 volts are present. The 5 volt supply is working.
The set originally took longer and longer to turn on.
Thanks.

Mike

Re: 20N60C3 question

i can't help you with this, but i'm also looking for a substitute.
i've got a 24V 5A power brick where the infineon "coolMOS" 20N60C3 (TO220) burned up. got hot enough to burn a nice mark into the aluminum heatsink and turn the TO220 tab purple..

wasn't able to find it anywhere except on ebay from who knows where for insane prices. most electronics suppliers have it listed, but out of stock

The w is for to-247 package. 20amp continuous, n channel, 600 volts. Digikey doesn't have this part #, but they have a few in the to-247 case (filter) and there are a few listed, but $10 is about the cheapest. Does it have to be a 247 case?

The data on these is fairly close at $4.44 each, but the in stock are to-220. The coolmos are metal oxide which I guess is why there aren't many subs.

Double check that number please. SWP ?? or SPW ???

Re: 20N60C3 question

Sorry, I transposed two letters in the part number. The SPW20N60C3 is the TO-247 case style and that is what I have.
Do you think the heat dissipation would be the same mounting a different case style part in the same location?

Re: 20N60C3 question

I would think so. The infineon site says these are up to C6 series and they don't make a 247 case in the new series. Digikey list your # as obsolete. bdent.com has your # at $10.35

Re: 20N60C3 question

I think I may have found a sub but at a higher cost. Currently, I'm looking at Digikey part number IPW60R075CPIN-ND Digikey has stock and it looks like this is Infineon's newer technology. The specs look more rugged to me - am I missing anything? Input capacitance is higher - does that matter that much?
Comments please!

Toasty,

Thanks for the info. Hopefully, I'll get the right part from Digikey when I speak with them tomorrow. Arrow's prices are good, looks like shipping is a flat $8.
