What materials are needed for semiconductors?
The most used semiconductor materials are silicon, germanium, and gallium arsenide. Of the three, germanium was one of the earliest semiconductor materials used. Germanium has four valence electrons, which are electrons located on the outer shell of the atom.
What kind of transistor is 2N3904?
NPN transistor
The 2N3904 is an extremely popular NPN transistor that is used as a simple electronic switch or amplifier that can handle 200 mA (absolute maximum) and frequencies as high as 100 MHz when used as an amplifier.
What is the most commonly used material in the manufacturing of semiconductors?
The material most frequently used in semiconductors is Silicon (chemical symbol = Si). Silicon is the second most abundant element on earth after Oxygen.
Where do the raw materials for semiconductors come from?
The semiconductor business has also become one of the most interlinked in history, with raw materials coming from Japan and Mexico and chips made in the US and China. The chips are then shipped around the world again to be installed in devices that end up in people’s hands in every country in the world.
Where are semiconductors used?
CPUs that operate personal computers are also made with semiconductors. Many digital consumer products in everyday life such as mobile phones / smartphones, digital cameras, televisions, washing machines, refrigerators and LED bulbs also use semiconductors.
What kind of transistor is 2N3904 datasheet?

How to identify a discrete semiconductor kit ( YB )?
You can consider the 2N3906 as the mirror-image of the 2N3904. The MOSFETs in the kit are smaller than the other transistors – the body is about half the size. Being smaller, there’s less room to print on them, so the part numbers are a terse code. The letters “YB” on the package are the identifier.
How big is 2N3904 in bytes and bytes?
