Prototyping and Engineering Tips from Robogears:

  • Always use an appropriate heatsink when driving high-current loads continuously to avoid thermal damage.
  • Add a flyback diode across inductive loads such as motors or relays to protect the MOSFET from voltage spikes.
  • For Arduino or ESP-based projects, use a proper gate resistor and ensure sufficient gate voltage for reliable switching performance.
