Frequently asked questions
Can I drive it directly from a 3.3V or 5V microcontroller pin?
Check the gate threshold and recommended gate-drive voltage in the datasheet first. Standard-level MOSFETs often need more gate voltage than a microcontroller pin provides, so a gate driver or a logic-level device may be required.
Does it need a heatsink?
For high-current loads, the TO-263 package needs adequate copper pad area or a heatsink. Estimate power dissipation from the on-resistance and the load current, and check the datasheet's thermal limits.
