The limitation arises predominantly from the common source inductance L S that is shared between the gate loop and the load circuit. To avoid this parasitic influence, advanced packages like the TO-247-4L or TO-263-7L …
The Kelvin source pin also affects switching loss. For instance, at 30 A I DS, the total switching loss in a TO-247-3 SiC MOSFET with no Kelvin pin and 12 nH source inductance is close to 430 μJ (Figure 5).The same product in a TO-247-4 package — with a Kelvin source pin — has merely 150 μJ of switching loss at the same I …

Since it is in series with the gate-source capacitance and gate driver and its polarity opposes the gate drive voltage being applied on the outside of the MOSFET package, this reduces the voltage the gate driver is able to apply across the gate-source capacitance so the MOSFET turns on slower. Something similar happens when turning off.

With the 600 V CoolMOS™ P6 SJ Infineon introduces an improved version of the standard TO-247 4-pin package. The TO-247 4-pin with asymmetric leads comes along with increased creepage distance between the critical leads and enables smoother wave soldering and reduced board yield loss. Benefits in efficiency of 4-pin versus 3-pin variants.
SiC MOSFETs are coming into prominence in select power switching applications above ½ kV, especially in those that benefit from the high-speed capability of SiC MOSFETs. This application note focuses on optimization for speed to minimize switching losses and to get the full benefit of the devices.
• The 900V 10 m SiC MOSFET chip is capable of extremely fast transitions. • In TO-247-3, LS in the gate driver loop will limit the switching speed.

A driver source pin is a new development in power MOSFET packaging technology. It provides a separate, low current terminal connection to the internal MOSFET source, separate from the high current drain to source path. Figure 2: Example of Gate drive circuit for MOSFET with driver source terminal. The gate to source voltage is thus …
Abstract—The behavior of 10 kV SiC MOSFETs during a flashover fault condition is investigated comprehensively. A larger turn-off gate resistance Rg,off is recommended for 10 kV SiC MOSFETs without Kelvin source to avoid very asymmetrical gate resistance, while a small Rg,off is recommended for 10 kV SiC MOSFETs with Kelvin source.
