## Frequently asked questions

### How does a Darlington differ from a MOSFET in use?

A Darlington is a current-driven device that needs base current, while a MOSFET is voltage-driven. Darlingtons also have a higher saturation voltage, so they dissipate more heat when fully on.

### Does it need a flyback diode?

Yes, when switching inductive loads such as motors or transformers. Use a heatsink and check the datasheet for the safe operating area at your voltage and current.
