## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Gate Driving
- Problem : Insufficient gate drive current causing slow switching and excessive switching losses
- Solution : Use dedicated gate driver ICs capable of delivering 2A peak current with proper rise/fall times
Pitfall 2: Thermal Management Issues
- Problem : Inadequate heatsinking leading to thermal runaway and premature failure
- Solution : Implement proper thermal calculations considering RθJA and maximum junction temperature (Tj max = 150°C)
Pitfall 3: Voltage Spikes and Ringing
- Problem : Parasitic inductance causing voltage overshoot during switching transitions
- Solution : Incorporate snubber circuits and optimize PCB layout to minimize loop inductance
Pitfall 4: Reverse Recovery Concerns
- Problem : Body diode reverse recovery causing current spikes in bridge configurations
- Solution : Implement dead time control and consider external anti-parallel diodes for high-frequency applications
### Compatibility Issues with Other Components
Gate Driver Compatibility:
- Compatible with standard MOSFET drivers (IR21xx series, TLP250, etc.)
- Requires minimum 10V VGS for full RDS(ON) performance
- Avoid drivers with slow rise/fall times (>
