The race to reduce power losses in semiconductor switches is being led by wide band-gap (WBG) devices and particularly SiC FETs, cascodes of a silicon carbide JFET and co-packaged silicon MOSFET. This arrangement produces a normally-off device with an easy gate drive and a trophy cabinet of ‘figures of merit’ th
