## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Considerations
- *Pitfall:* Insufficient gate drive current causing slow switching and increased losses
- *Solution:* Use dedicated gate driver ICs capable of delivering 1-2A peak current
- *Pitfall:* Gate oscillation due to layout parasitics and high di/dt
- *Solution:* Implement gate resistors (2-10Ω) and minimize gate loop area
Thermal Management
- *Pitfall:* Inadequate heatsinking leading to thermal runaway
- *Solution:* Calculate thermal impedance and select appropriate heatsink
- *Pitfall:* Poor thermal interface material application
- *Solution:* Use proper thermal compound and mounting torque (0.6-0.8 N·m)
Overvoltage Protection
- *Pitfall:* Voltage spikes exceeding VDS(max) during inductive switching
- *Solution:* Implement snubber circuits and TVS diodes for protection
- *Pitfall:* Avalanche energy exceeding rated capability
- *Solution:* Design for safe operating area with adequate derating
