    TVS junction capacitance reverse voltage

    Is a MOSFET or IGBT gate driver sinking current into the junction capacitance at Vreverse or somewhere between V=0bias and Vreverse in a TVS diode?

    Re: TVS junction capacitance reverse voltage

    Don't know what "sinking current into" means. I guess you want to estimate the additional gate driver load caused by a TVS diode. For an exact calculation, you need to know the diode C/V characteristic. For a first estimation, you can calculate with the diode capacitance at actual gate voltage, slightly higher than C(VR).

    If TVS diodes actually provide any protection for your MOSFET and IGBT is a different question.
