    Question about the voltage-class

    Hey all,
    is it mandatory to use -5V during turn-off? Can 0 V be used?

    I believe you are asking the gate voltage window.

    For the gate voltage, please follow the application note. 0V is recommend for the discrete devices.

    Also for the Easy modules 0 V can be used in case simplicity of the design has priority vs. switching speed. With a higher turn-on gate resistor the dV/dt can be reduced to a level that also modules - inspite of their longer internal and external gate connections - can be operated with 0 V. In some applications - like drives - dV/dt needs to be limited anyhow to avoid adverse effects on the machine windings and bearings.
