Hello @wanglipeng00000,

This really depends on the specific application conditions, such as switching frequency, operating temperature, etc

Hello @wanglipeng00000!

You can make a rough calculation according to the driving current of the IRS21864S and the Qg of the...IRFS4115, Qg=I*tr, and then estimate an acceptable tr time according to the switching frequency of 10kHz and the switching cycle of 100us, and then add some margin according to the actual situation, so that you can roughly get a value.
