Recharging the Batteries

It has been a mixed year so far, with plenty of innovation on display, but a flat economy put a bit of a spoiler on the industry. The forecast for next year is pretty mixed too, with some people predicting a global recession. As the old saying goes, economists have predicted eight of the last three recessions, so

Figure 1. Comparing SiC with conventional Silicon MOSFETs reveals the clearly superior semiconductor characteristics of the SiC material, which allows the construction of significantly smaller switching devices

SiC MOSFET Efficiency and Protection without Compromise

Thorsten Schmidt, Technical Product Manager, Power Integrations

The lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity – valuable in space saving applications. In addition, the electric-breakdown- field for SiC (approximately 2.8 MV/cm) allows for a much shorter isolati
