2. Application hints

 Gate resistors

The gate resistors can be assembled via SMD process. Gate resistors values should be chosen as low as

possible to have low switching losses. But over voltages over the full temperature range during standard

switch off and during short circuit switch off are the limiting factor and must be checked.

 Active Clamping/ SoftOff

The active clamping has to be set according to the required DC link voltage and has to be proven during

short circuit conditions.
