Term
Anode
Definition
The element of an electronic device that receives the flow of electron current.
Term
Bulk Resistance
Definition
The Ohmic resistance of the semiconductor material.
Term
Cathode
Definition
The element of an electronic device that provides the flow of electron current.
Term
Ideal Diode
Definition
The first approximation of a diode. The viewpoint is to visualize the diode as an intelligent switch that closes when forward-biased and opens when reverse-biased.
Term
Knee Voltage
Definition
The point or area on a graph of diode current versus voltage where the forward current suddenly increases. It is approximately equal to the barrier potential of the diode.
Term
Linear Device
Definition
An ordinary resistor. Current versus Voltage on graph is straight line.
Term
Load Line
Definition
A tool used to find the exact value of diode current and voltage.
Term
Maximum Forward Current
Definition
The maximum amount of current that a forward-biased diode can withstand before burning out or being seriously degraded.
Term
Nonlinear Device
Definition
A device that has a graph of current versus voltage that is not a straight line. A device that cannot be treated as an ordinary resistor.
Term
Ohmic Device
Definition
Term
Ohmic Resistance
Definition
Term
Power Rating
Definition
The maximum power that can be dissipated in a component or device that is operated according to a manufacturer's specifications.
Term
Up-down Analysis
Definition
A method of analyzing an electronic circuit using independent and dependent variables. When an independent variable (such as a voltage source) is increased or decreased, the resulting dependent variable (resistor voltage drop or current) change is predicted.
