   UN Regulation 37 covers motor vehicle filament lamps. These are categorized in three groups: those without general restriction that can be used in any application, those acceptable only for signalling lights (not for road illumination lamps), and those no longer allowable as light sources for new type approvals but still permitted for production as replacement parts.

   MELF: Metal electrode leadless face (usually for resistors and diodes) SOD: Small-outline diode. SOT: Small-outline transistor (also SOT-23, SOT-223, SOT-323). TO-XX: wide range of small pin count packages often used for discrete parts like transistors or diodes. TO-3: Panel-mount with leads; TO-5: Metal can package with radial leads

7. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   In an organic light-emitting diode , the electroluminescent material composing the emissive layer of the diode is an organic compound. The organic material is electrically conductive due to the delocalization of pi electrons caused by conjugation over all or part of the molecule, and the material therefore functions as an organic semiconductor ...

8. Voltage regulator - Wikipedia

   en.wikipedia.org/wiki/Voltage_regulator

   A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V-I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input. When precise voltage control and efficiency are not important, this design may ...

9. 1N4148 signal diode - Wikipedia

   en.wikipedia.org/wiki/1N4148_signal_diode

   Cross section of a 1N914 in glass axial package. As the most common mass-produced switching diode, the 1N4148 replaced the older 1N914. They can be used interchangeably, and are cross-reference replacements for each other. They differed mainly in their leakage current specification, however, today most manufacturers list common specifications.
