How to Select CR Micro MOSFETs for Your Application
How to Select CR Micro MOSFETs
Introduction
CR Micro offers a comprehensive portfolio of power MOSFETs covering voltage ranges from 20V to 900V. This guide will help you navigate the selection process.
Key Selection Criteria
1. Voltage Rating Selection
- Low Voltage (20-100V): DC-DC converters, motor drives, battery management
- High Voltage (500-900V): SMPS, LED drivers, solar inverters
2. Current Rating
Calculate based on RMS current, peak current, and safety margins.3. RDS(on) Considerations
Lower RDS(on) reduces conduction losses but may increase cost and gate charge.4. Switching Performance
Consider gate charge (Qg) and switching times for high-frequency applications.Selection Decision Tree
Conclusion
CR Micro MOSFETs offer excellent price-performance ratio for various applications.
