- Pitfall : Excessive gate ringing due to poor layout
- Solution : Use short, direct gate traces and include series gate resistors (2-10Ω)
Thermal Management Problems
- Pitfall : Inadequate heatsinking leading to thermal runaway
- Solution : Calculate thermal requirements using θJA and provide sufficient copper area
- Pitfall : Poor thermal interface material application
- Solution : Use high-quality thermal pads or thermal grease with proper mounting pressure
Parasitic Inductance Issues
- Pitfall : High di/dt causing voltage spikes and potential device failure
- Solution : Minimize loop area in power paths and use low-ESR decoupling capacitors
### Compatibility Issues with Other Components
Gate Drivers
