Additional Details

The 30CTQ080S is typically packaged in a TO-220AC or similar through-hole package. Key specifications include a maximum repetitive peak reverse voltage (VRRM) of 80V and an average forward current (IF(AV)) of 30A. The forward voltage drop is typically around 0.65V at the rated current. It is essential to consult the manufacturer's datasheet for detailed electrical characteristics, thermal resistance values, and application guidelines. Proper heat sinking is critical for reliable operation at high currents and temperatures.
