The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

The 2SA1648 is a PNP silicon epitaxial transistor featuring fast switching speed for high current control. It features low collector saturation voltage, as well as high DC current gain and excellent ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

Researchers at the University of Southampton develop a new graphene transistor with 1000 times higher on/off switching ratio. The new transistor achieves a record high-switching performance which will ...

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (DIOD) today announces an expansion of its automotive-compliant* bipolar transistor portfolio with the introduction of the DXTN/P 78Q & 80Q series.

The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and ...

Shockley had continued his semiconductor work, and in 1948 patented the modern junction transistor. Three years later, Bell Labs demonstrated part number M1752 ...

Researchers at Southampton University have developed a graphene transistor with an on/off switching ratio that is 1,000 times higher than in previous devices. A new transistor made from graphene — the ...

It's not like you can see it by looking at the case of iPod or PC, but without the transistor, we would have none of the "magic" electronic devices we now know and cannot live without. Shockley had ...
