4.1 Typical Switching Waveforms with WAB300M12BM3

Switching waveforms during hard switching of the semiconductors are measured with an oscilloscope using the standard
double-pulse test procedure. The SiC MOSFET module used for testing is the Wolfspeed SiC MOSFET WAB300M12BM3.
Figure 28 shows the turn-on switching transient, while Figure 29 depicts the turn-off switching transient at different drain
current levels. The switching performance measurements were carried out with the default gate resistor values, 2.95Ω for
both On and Off resistors, and a +14V/–4V gate power supply.

voltage waveforms are depicted with solid lines, and current waveforms are depicted with dashed lines.
