EUPEC INFINEON FZ1200R16KF4 FZ1200R17KF4 IGBT NEW OLD AND FAKE The purpose of this document is to guide the reader regarding the authenticity of this FZ1200R17KF4 / FZ1200R16KF4 IGBT which are found in EBay and some shops selling this product. EUPEC is a German igbt manufacturer start is the 1990, a subsidiary of Infineon Technologies. It very popular and has been used on frequency inverter. In 2005, Eupec is integrated to Infineon. It's very hard to find this product now days as brand new and there are many igbt of this type sold as refurbished. After few years working in this product, this is what I find out. The picture above is original brand new 2011 igbt we bought from Infineon, it's been tested and working fine on frequency converters, take note that it uses INFINEON as a brand. Original Eupec IGBT Picture above are igbts that has been remove from original German made inverters. We tested them and seems to be they are original and they pass current sharing test and VCEsat testing. Fake IGBTs in the Market We bought this IGBT in Asian Market, they seems to be brand new is what they say, but looking closely to the terminal, the terminal in the collector and emitter is thinner than the original, and when you buy them, there is bolt and nut included .Look also on the date code and compare them to the original. We have used this igbt and they all exploded on the system. What a big mess. So we carefully inspected them and put on test. The vcesat voltage is far fron the spec, and there is a big imbalance on the branches more than 30 percent . The label looks perfect but they peel off when they heat up. Just be careful because, when we bought the first batch of 10 pcs, they seems to be original, then we bought a second batch of 50 pcs and they were all fake, and we return it, the seller told us that the fake and original was mix up. On the conclusion, this seller is mixing original and fake unit on big orders So we never bought again from Asian Market. These companies even have ISO certifications. We have develop a test setup to test this igbts. Using a high current source 160 amps, we'll be able to confirm the Vcesat and the current sharing on the unit under test. The current sharing is both tested on DC and AC pulse width modulation. We are reselling the old igbts that we pull out from the GERMAN made inverters, they are screened and pass all the test, if you're interested pls email us.
