Hello

I am developing a PFC and considering IKW40N65WR5 as a switching device.
My question is what’s the maximum switching frequency of IKW40N65WR5?
Is it okay to use for 60~70kHz?

Thanks in advance.

Hello Melli,

You have the right choice for high switching frequency operation.
IKW40N65WR5 is exactly optimized device for PFC application that doesn't require high performance of co-pak diode.
Based on our internal examination it allows the switching frequency up to 75kHz and performs similar or better than equivalent SJ MOSFET (80mohm CoolMOS P7).
The data below can help you.
