A gate line beside three broken channel segments.
Also known as: Enhancement mode MOSFET, E-MOSFET, Normally off MOSFET, Broken line transistor
A broken channel line in a MOSFET symbol means enhancement mode: the device is off with no gate voltage and must be turned on. A continuous line means depletion mode, which conducts until turned off — and that single difference between broken and solid decides whether a circuit is safe at power-up.
Denotes an enhancement-mode MOSFET: non-conducting at zero gate-source voltage and turned on by an applied gate voltage.
Contexts: Electrical equipment
Is drawn with the channel as three separate segments, against the continuous line of the depletion-mode symbol.
Contexts: Electrical equipment
Carries a body diode between source and drain in most power devices, drawn explicitly, which conducts in one direction regardless of the gate.
Contexts: Electrical equipment
A vertical gate line separated by a gap from three short vertical channel segments, with drain and source leads from the outer two and an arrow on the substrate lead.
