A MOSFET uses gate voltage to route or regulate current. Explore its roles in switching, amplification, power conversion, motor control, and protection.
Follow a MOSFET through a practical low-side switching circuit, from gate drive and current flow to body-diode action, loss, layout, and protection.
A practical framework for balancing conduction loss, switching behavior, and thermal margin in offline power converters.
A measurement-led method for choosing gate resistance without trading away more efficiency, voltage margin, or EMI performance than necessary.
Learn how to translate an inrush or fault event into an SOA operating point and verify that a MOSFET can survive linear-mode stress.
