2. 1N400x rectifier diode - Wikipedia

   en.wikipedia.org/wiki/1N400x_rectifier_diode

   1N400x rectifier diode. The 1N400x (or 1N4001 or 1N4000 [ 1]) series is a family of popular one- ampere general-purpose silicon rectifier diodes commonly used in AC adapters for common household appliances. Its blocking voltage varies from 50 volts (1N4001) to 1000 volts (1N4007). This JEDEC device number series is available in the DO-41 axial ...

3. 1N4148 signal diode - Wikipedia

   en.wikipedia.org/wiki/1N4148_signal_diode

   Diode schematic symbol vs cathode marking on the package. The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and long-lived switching diodes because of its dependable specifications and low cost. Its name follows the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a ...

4. Diode - Wikipedia

   Electron flow is the reverse of conventional current flow. [ 1][ 2][ 3] 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.

5. Zener diode - Wikipedia

   en.wikipedia.org/wiki/Zener_diode

   The two types of diode are in fact constructed in a similar way and both effects are present in diodes of this type. In silicon diodes up to about 5.6 volts, the Zener effect is the predominant effect and shows a marked negative temperature coefficient. Above 5.6 volts, the avalanche effect dominates and exhibits a positive temperature coefficient.

6. Diode logic - Wikipedia

   en.wikipedia.org/wiki/Diode_logic

   Designers must rely on a diode's specification sheet, which primarily provides a maximum forward voltage drop at one or more forward currents, a reverse leakage current (or saturation current), and a maximum reverse voltage limited by Zener or avalanche breakdown. Effects of temperature and process variation are usually included. Typical examples:

7. Schottky diode - Wikipedia

   en.wikipedia.org/wiki/Schottky_diode

   The Schottky diode (named after the German physicist Walter H. Schottky ), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.
