Frequently Asked Questions
What package should I choose for high current?
For high current applications: DPAK handles up to ~10-12A with good PCB copper. D2PAK handles 15A+ with adequate thermal design. TO-220 and TO-263 are also options for through-hole or high-power surface mount. Consider thermal resistance from junction to ambient for your specific PCB design.
Choose package based on current and thermal requirements. D2PAK recommended for 15A operation.
