## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues:
- Pitfall : Inadequate heat sinking leading to thermal runaway
- Solution : Calculate thermal impedance and use appropriate heat sink with thermal compound
- Implementation : Maintain junction temperature below 150°C with safety margin
Gate Drive Problems:
- Pitfall : Insufficient gate drive current causing slow switching and increased losses
- Solution : Use dedicated gate driver IC with peak current capability >6A
- Implementation : Implement negative turn-off voltage (-5V to -15V) for reliable operation
Overcurrent Protection:
- Pitfall : Lack of proper desaturation detection
- Solution : Implement desaturation detection circuit with blanking time
- Implementation : Use current sensors or shunt resistors for real-time monitoring
