Coppell TV Repair offers you one or more units of Infineon's 17N80C3 power transistor in its TO-247-3 package version.
The official name for this release is SPW17N80C3.
As with most of our parts for sale we use them ourselves in our repair services meaning you will end up using a component that we ourselves would have used.
We do not offer warranty on components other than DOA meaning that you can return the component if you do not like the way it looks or how it tests to a meter...anything, but solder it and use it on a live circuit.
Once soldered or with cut legs the resposibility for its life is too much out of our hands and we can not afford to support it.
