## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- *Pitfall*: Insufficient gate drive current causing slow switching and increased losses
- *Solution*: Implement gate drivers capable of ±20A peak current with proper decoupling
Thermal Management
- *Pitfall*: Inadequate heatsinking leading to thermal runaway
- *Solution*: Use thermal interface materials with thermal resistance <0.1°C/W and forced air/liquid cooling
Overcurrent Protection
- *Pitfall*: Desaturation detection delay causing device failure during short circuits
- *Solution*: Implement fast desaturation detection with blanking time <2μs and soft shutdown
Voltage Spikes
- *Pitfall*: Excessive voltage overshoot during turn-off destroying the device
- *Solution*: Utilize low-induance busbar design and snubber circuits
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires isolated gate drivers with minimum 15V supply voltage capability
- Compatible with: 1ED020I12-F2, 2SC0435T, ACPL-332J
- Incompatible with: Non-isolated drivers, drivers with <10A peak current capability
DC-Link Capacitors
- Requires low-ESR film or electrolytic capacitors close to module
- Recommended: EPCOS B25620 series, Cornell Dubilier 940C series
- Avoid: High-ESL capacitors distant from module terminals
