(Picture right, an early version of the Telefunken logo featuring the sparks (funken) associated with wireless of the time.) In the pre-history of semiconductors material science, Karl Ferdinand Braun had discovered in 1874 that metal sulphides showed unidirectional conductivity.
Atom Power, inventor of the world''s first and only true digital circuit breaker, today unveiled the second generation of its breakthrough technology. The Generation 2 Atom Switch is now UL Listed to UL 489I — the standard listing for solid-state circuit breakers. In
(2) A type of vacuum tube used in electronic circuits as a rectifier or radio frequency detector. Modern appliions of tube diodes are generally limited to rectifiers in high-end audio amplifiers and other specialized high-voltage circuits. The tube diode uses two
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it.Electrons in the semiconductor recoine with electron holes, releasing energy in the form of photons.The color of the light (corresponding to the energy of the

21/5/2020· Compared to its silicon (Si) counterparts, it is more critical for silicon carbide (SiC) devices due to the reliability concern introduced by the immaturity of new material and packaging. This paper proposes a practical implementation using an intelligent gate drive for online junction temperature monitoring of SiC devices based on turn-off delay time as the thermo-sensitive electrical parameter.

For the 1N4148 diode, the breakdown voltage is very large. If we can build a different type of diode with this voltage in a useful range (a few volts to a few hundred volts), we can use such devices to regulate voltages. This type of diode is called a Zener diode because
Diodes manufactured from silicon carbide are capable of high temperature operation to 400 o C. This could be in a high temperature environment: down hole oil well logging, gas turbine engines, auto engines. Or, operation in a moderate environment at high power
