Then knowing he needed 4 mA to power each LED for backlighting he used some 1978 vintage current limiting diodes designed to pass 2mA each regardless of voltage source, within limits of course.

They have none of the special skills you’d find in tunnel, Gunn, varicap, Zener, and avalanche diodes, or even LEDs, instead they are simply a one-way valve for electrical current. Connect ...

By putting in four layers, instead of the three used in transistors, the Shockley Diode could do more than a transistor. For one, it acted like a rectifier, able to turn alternating current into ...

Diode The diode is a two-terminal electronic component that allows an electric current to pass in one direction (low resistance) while blocking it in the reverse direction (high resistance). The diode ...
