An IGBT for controlling the application of power to a plasma display panel has an increased current conduction capability and a reduced conduction loss at the expense of a reduced safe operating area. For a device with a 300 volt breakdown voltage rating, the die has a substrate resistivity less than 10 m ohm cm; a buffer layer thickness of about 8 μm resistivity in the range of 0.05 to 0.10 ohm cm, and an epi layer for receiving junction patterns and trenches, which has a thickness of from 31 to 37 μm and resistivity in te range of 14 to 18 ohm cm.
