Cables

Therefore, the datasheet value is quite low compared to a calculated value based on theory, but it specifies a safe operation considering all practical limitations of the power module. 

This parameter describes safe operating conditions at turn-off for the IGBT. The chip can be driven within its specified blocking voltage up to twice its nominal current rating, if the maximum temperature under switching conditions is not exceeded. The safe operating area of the power module is limited due to the module’s internal stray inductances and specified at the maximum temperature under switching conditions as shown in Figure 8. With increasing currents, the allowed DC-Link voltage is decreased. 

Furthermore, this derating strongly depends on system related parameters, like stray inductance of the DC-Link and the current commutation slope during the switching transitions. The DC-Link capacitor is assumed to be ideal for this operating area. The current commutation slope is defined via a specified gate resistance and gate driving voltage. In no event the voltage spike must not exceed the specified voltage of the module at the terminals or at chip level to keep the RBSOA limits.
