## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues :
- Pitfall : Inadequate heat sinking leading to thermal runaway
- Solution : Implement proper thermal calculations and use appropriate heatsinks
Voltage Spikes :
- Pitfall : Unsuppressed inductive kickback exceeding PIV rating
- Solution : Incorporate snubber circuits or TVS diodes for protection
Current Overstress :
- Pitfall : Exceeding average forward current rating
- Solution : Derate current by 20-30% for reliability and include fusing
### Compatibility Issues with Other Components
Capacitive Loads :
- High inrush currents during startup can stress the diode
- Use soft-start circuits or current-limiting resistors
Inductive Loads :
- Generate reverse voltage spikes during turn-off
- Implement freewheeling paths with appropriate snubbers
Parallel Operation :
- Current sharing issues due to parameter variations
- Use individual series resistors or select matched devices
### PCB Layout Recommendations
Power Routing :
- Use wide copper traces (minimum 2mm width for 1A current)
- Maintain adequate clearance (≥1.5mm) between high-voltage nodes
Thermal Management :
- Provide sufficient copper area around diode mounting
- Use thermal vias for heat dissipation to inner layers
- Position away from heat-sensitive components
EMI Considerations :
- Keep loop areas small in rectifier configurations
- Use ground planes for noise reduction
- Implement proper filtering near diode connections
