Eupec IGBT part number FZ1200R17KF4. These units have a thermistor glued to the side of the baseplate (see photos). Our supplier sold these to us unused, but we are pricing them as used because of the addition of the thermistor. We also have new units available
here. There are additional part numbers printed on an extra label as follows (see picture): G-01-0167-F-12 75345A06 77430
