The default desaturation detection time is 3uS, so if you are switching fast, the datasheet suggests just to leave out Ctrip. They only recommend it if you are using large gate resistors to slow the switching way down.

Cs allows for a softer shut down when there's a desaturation detection. The default soft turnoff time with no Cs is about 9uS. If that's not slow enough, Cs = 100pF has turnoff time of 13uS, all the way to Cs = 800pF giving a turnoff time of 47uS.
