Generally speaking, which will turn off or on faster? An IGBT or a MOSFET?

I know there are pros to both. But I'm leaning toward an IGBT for a project.

 

MOSFET are faster then there are SiC mosfets that are faster yet and now GAN fets that are really fast.

What voltage and current do you want to switch?

 

Yes, definitely depends on what kind of MOSFET you're implementing. I'm partial to SiC MOSFETs in my designs at the moment.

 

What I have for the MOSFET

Tdon: 10% of gate voltage to 90% of collector voltage

Tr: 90% to 10% of collector voltage

Tdoff: 90% of gate voltage to 10% of collector voltage

Tf: 10% to 90% of collector voltage

 

Quick question –

would i be able to estimate the switching parameters of an IGBT using collector voltage?

 

This could help to calculate that ..

This is the formula I will always remember for this exact need.

Vce = Vcc - IcRc

 

would i be able to estimate the switching parameters of an IGBT using collector voltage?

No but by looking at the data sheet and current and voltage and drive conditions and .....
