- Pitfall : Excessive gate ringing due to layout inductance
- Solution : Implement tight gate loop with series gate resistor (2.2-10Ω typical)
Thermal Management
- Pitfall : Inadequate heatsinking leading to thermal runaway
- Solution : Calculate power dissipation and select appropriate heatsink using:
```
TJ = TA + PD × (RθJC + RθCS + RθSA)
```
- Pitfall : Poor PCB thermal design
- Solution : Use thermal vias and adequate copper area for heat spreading
Protection Circuits
