## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues:
- Pitfall : Insufficient gate drive current causing slow switching and excessive switching losses
- Solution : Implement dedicated gate driver IC with minimum 2A peak current capability
- Pitfall : Gate oscillation due to poor layout and excessive trace inductance
- Solution : Use twisted pair or coaxial cable for gate connections, implement gate resistors (4.7-10Ω)
Thermal Management:
- Pitfall : Inadequate heatsinking leading to thermal runaway
- Solution : Calculate thermal impedance requirements based on maximum power dissipation
- Pitfall : Poor thermal interface material application
- Solution : Use high-quality thermal pads or thermal grease with proper mounting torque
