Frequently Asked Questions
1. How much copper area do I need for SMB packages?
For 5A continuous in SMB: minimum 1 square inch copper. for 10A: 2+ square inches or external heat sink. Use thermal vias to connect layers.
2. How do I apply Thermal Design for Power Diodes principles in my design?
Start by understanding your application requirements including voltage, current, and thermal constraints. Follow the step-by-step guidelines in this article, and use the provided formulas for calculations. Validate your design with prototype testing and thermal measurements.
3. What tools do you recommend for thermal analysis?
We recommend using thermal simulation software for initial design, followed by prototype validation with thermocouples or thermal imaging. Our FAE team can provide thermal modeling support for complex designs.
4. How can I get additional technical support?
Contact our FAE team through the support portal, email, or phone. We offer design review services, thermal analysis support, and application-specific recommendations. For complex projects, we can arrange on-site support.
