infineon JFET Cascode电流应用CASCODE LIGHT - normally-on JFET stand alone performance in a
normally-off Cascode circuit

Abstract
SiC power devices are known to show best performance in terms of switching losses. Since the SiC
Schottky-barrier diodes became commercially available in 2001, transistors are in the focus of devel-
opment. Because of its electrical behaviour and reliability, the SiC normally-on JFET seems to be one
of the best candidates for future low loss unipolar switch application [1]. For safety reasons at startup
and in failure mode, circuit designers aiming at normally-off switch characteristic. Therefore, nor-
mally-on high voltage SiC JFETs were combined with standard low-voltage MOSFETs forming a nor-
normally-off Cascode circuit
