I have question about how to use Coss of SIC MOSFET to calculate right Qoss?
Is there use Qoss = Coss*VDS@600V math formula? please advise.
This is a SiC MOSFET AIMW120R045M1 switching characteristics test circuit:
And AIMW120R045M1 switching characteristics SPEC:

I am planning to use this MOSFET BSC026N08NS5 for my one of the Power Redundancy circuit, i just wanted to know if this MOSFET can be used for Automotive Application. The operating temp range of this MOSFET given in Datasheet is -55'c to 150'c.
In general, I think that the lower the Rdson of the MOSFET, the greater the current that can flow.
However, when comparing CoolSiC's 650V, TO-247-3 package products, IMW65R027M1H (27mΩ, 47A) has a lower Rdson than MW65R030M1H (30mΩ, 58A), but the ID that can flow is also lower.
Why is this?

I have recieved a new production lot for IRF7437PBF mosfet which is different from the previous lot.
1. New mosfet don't have cut as compared from the previous lot.
2. Marking Font is different.
Image attached for better understanding. I have not received any change notification from infineon for the same.
Please reply ASAP, production is on hold.Show Less
Did Infeneon have software state machine (Block diagram) of Infineon Eva board "EVAL_3K3W_TP_PFC_SIC"?
i tried to find in application note but it doesn't have.
For the output capacitance Coss exist two equivalent fixed capacitance:
- Co(tr): Effective output capacitance, time related. It's a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 400V.
- Co(er): Effective output capacitance, energy related. It's a fixed capacitance that gives the same stored energy as Coss while VDS is rising from 0 to 400V.
The effective output capacitance is based on measurements. These values take the change of capacitance into account without the need for complex formulas.
For the dead-time calculation, e.g. for the LLC-Converter, the effective output capacitance should be used.
Why do Coss, Co(er) and Co(tr) differ so much?
Why is Co(tr) used for dead-time calculation, e.g. for the LLC-Converter, and not Co(er)?
Why is still sometimes the Coss used for the dead-time calculation?
Can you please share the Vds vs Vgs characteristic graph for SPD30P06P G ?
I could not find in the datasheet.
I would like to request for the junction-to-board thermal resistance (Theta_JB) information for IRFH5110PbF.
Thank you!Show Less
