Hi infineon 

1. Did you know what's reason to define the Rg 5.1 ohm on datasheet ?  Consider EMI & power loss ? spec cross EMI.

2. Did you know Rg set  lower than Rg 5.1 ohm? Any impact ?

3. Could you test report for Eon/Eoff ? Any test report can be provide ?

Thanks

Hi Brian,

1. Rg 5.1 Ohm is for lower power loss, and relative good Vce,spike

2. You can set Rg lower than 5.1Ohm. Keep Vce,spike, gate voltage spike and oscillation under control, cause these factors could go higher. In this situation, switch loss won't decrease too much.

3. There is diagram in datasheet of Eon/Eoff in different Rg for you reference.

Thanks and BR,

Steven

@Jingwei

 Could you shared the data Rg vs Eon/Eoff  ? Because i can't find on datasheet
