There is an impression that the capability of small form factor surface mount device (SMD) packages in handling current and heat is limited. This is not true, at least the limitation does not come from the package itself. For example, in an application note, Infineon shows that the continuous current rating of power MOSFET

 Silicon carbide (SiC) Schottky rectifiers are extremely fast with zero minority carrier (hole) reverse recovery charge (Qrr). The only charge participated during the switching of SiC Schottky Rectifiers is the majority carrier (electron) junction capacitive charge (Qc). The Qc of SiC Schottky Rectifiers does not change with temperatures or operation conditions such as forward current
