I V characteristic of a semiconductor diode
a Set up the circuit as shown below.. b Use the variable power supply and the variable resistor to vary the potential difference across the diode from 0 V to 0.8 V in intervals of about 0.1 V. Record pairs of potential difference and current values. Repeat in the range 0 V to 4.0 V in intervals of 0.5V, by reversing the connections on the diode. c Analysis.Diode
A diode is a two terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from ...Laser diode
A laser diode, (LD), injection laser diode (ILD), or diode laser is a semiconductor device similar to a light emitting diode in which the laser beam is created at the diode's junction. Laser diodes can directly convert electrical energy into light. Driven by voltage, the doped p n transition allows for recombination of an electron with a hole.Due to the drop of the electron from a higher ...Semiconductor Basics Basic Electronics Tutorials
Semiconductor Basics. If resistors are the most basic passive component in electrical or electronic circuits, then we have to consider the Signal Diode as being the most basic active component.Physical Explanation Vishay

Parameter t a is the interval between the zero crossing of the diode current to it reaches I RR.Parameter t b is the time interval from the maximum reverse recovery current to 0:25 of I RR.. The lower t rr means fast diode switching. The ratio of the two parameters t a and t b is known as the softness factor SF..
