I am designing a clamping circuit for an IGBT driver such as ABB 5SNA 0600G650100.Between the collector and the IGBT gate there will be a set of TVS diodes with a Schottky diode at the end. The gate will have a 6.8k pull-down resistor to the emitter ...

I am designing clamping circuit for IGBT driver. The max voltage is 4800V. I was thinking about using STTH112A diode. In the datasheet, there is no information about thermal resistance - junction to ambient for SMB or SMBflat version. How can I asses...
