InventChip SiC MOSFET Selection Guide
Selecting the right InventChip SiC MOSFET is critical for achieving optimal performance. This guide covers key selection criteria including voltage rating, current rating, on-resistance, and cost considerations.
Voltage Rating Selection: Choose a voltage rating at least 1.3 times the maximum DC bus voltage. For 400V EV systems, select 650V devices. For 800V systems, select 1200V devices. Consider voltage spikes during switching.
Current Rating Selection: The continuous drain current rating should be at least 1.5 times the RMS current. Consider both continuous and peak current requirements. InventChip offers competitive Rds(on) specifications.
Cost Considerations: InventChip devices offer 20-30% cost savings compared to international brands while maintaining comparable performance and quality. This makes them ideal for cost-sensitive applications.
Package Selection: TO-247 packages are suitable for most applications. Consider thermal requirements when selecting packages.
