Fast diode between gate and supply pin
On all low and high side drivers a fast diode is provided to clamp the gate coming over the V
supply pins and to recover the current coming from the collector node through the gate-collector
capacitance.
The following table shows the names of these components on board.
Zener diode to preserve the IGBT gate
