### PCB Layout Recommendations
Power Path Optimization :
- Use wide copper traces for drain and source connections (minimum 2mm width for 5A current)
- Implement ground planes for improved thermal dissipation and noise immunity
Gate Drive Circuit Layout :
- Keep gate drive loops compact and minimize parasitic inductance
- Place gate resistors close to MOSFET gate pin
- Use separate ground returns for gate drive and power circuits
Thermal Management :
- Provide adequate copper area under DPAK package (minimum 6cm² for full current rating)
- Use thermal vias to inner layers or bottom side for enhanced heat spreading
- Consider solder mask opening over thermal pad for improved thermal transfer
Decoupling Strategy :
- Place 100nF ceramic capacitor close to drain-source terminals
