I want to find a product with FWD Diode in C3M0032120K sic-mosfet.

But it doesn't come out well when I search it

FWD Diode : C4D20120A

TBhatia

Hello Advance,

Can you please clarify? All SiC MOSFETs have a parasitic body-diode from source to drain that can be used as a free-wheeling diode. It is however a regular diode with reverse-recovery. Please see the body-diode characteristics in the datasheet of C3M0032120K on pages 3 & 5.

Are you saying you're looking for a device with an additional diode in parallel with body-diode of C3M0032120K? Thanks!

Thank you for your answer

Could you look at the 8 page Fig.26 Clamped Inductive Switching Energy vs. Teature graph in the data sheet you sent me as a link?

FWD = C3M0032120K

FWD=C4D20120A

There are two Sweeting Loss graphs like this.

So I'm looking for a product where C4D20120A is connected as an additional diode to C3M0032120K like the graph of FWD = C4D20120A

Hello Advance,

Thank you for the clarification. For Fig.26, C4D20120A is not connected as an "additional diode" to C3M0032120K. C4D20120A is only switch in the top position for Clamped Inductive Switching test and C3M0032120K is the DUT. Please find schematic below:

Wolfspeed doesn't have a product where an additional diode is placed in the same discrete package as the MOSFET die. However, it is possible to achieve this in a design using 2 separate (MOSFET and external diode) packages. Let me know if you have any other questions. Thank you!
