Coupling heatsink RC network to MOSFET's Cauer circuit
I am trying to understand simple RC thermal simulation to analyse the temperature rise in Rohm a 1200 V N-channel SiC MOSFET SCT3040KR.
RC Cauer parameters are as depicted in the LTspice circuit ...

What does the cross point of V-I curves mean?
Here you see a V-I graph including many curves achieved under different junction temperatures of an IGBT. As it can be seen there is a cross point where all curves intersect each other. Does it make ...

IGBT chip metalization
Consider an IGBT chip within a power module.
The top surface of the chip is often metalized by aluminum (with approximately 5 microns thickness) to bond some aluminum wires into the chip; I am hazy ...

Ic and Vce equations of IGBT
I know in IGBTs while operating, parameters Ic (collector current) and Vce (collector-emitter voltage) are Tj (junction temperature) and Vge (gate-emitter voltage) dependent. Is there anything else ...

Input capacitance IGBT and MOSFET
I measured the input capacitance of a MOSFET and found it was greater than an IGBT. Why is this? Is it due to the Miller capacitance seen in a MOSFET?
