Hello,

I am wondering how long it would take to switch IGW30N60TPXKSA1on with 5 ma of current at 20 volts. Would this be ok for a frequency of around 1KHZ? The gate charge is 167 nC

To completely charge or discharge 167 nC, you need to integrate the constant current of 5mA over some time interval Δt. So we have:

\( \Delta t\;=\;167\;\text{nC}/5\;\text{ma}\;=\;33.4\;\mu \text{sec} \)
