N-channel MOSFETs
Low-side switches — Vgs, Rds(on), and package.
An NMOS used as a low-side switch turns on when Vgs exceeds the threshold in the datasheet. Logic-level parts reach low Rds(on) at 4.5 V drive.
Checklist
- Vds rating above supply spikes
- Rds(on) at your actual Vgs, not only 10 V test conditions
- Qg if you switch fast from a GPIO (gate charge affects switching loss)
