alloy junction การใช้

• General Electric pioneered the alloy junction transistor process for germanium transistors.
• The 2N43-45 series was GE's first commercial alloy junction transistor using the 2N numbering system.
• Like Raytheon's CK722, the GE 2N107 were fallouts or rejects of GE's successful 2N43, 2N44 and 2N45 alloy junction transistors.
• In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy.
• Raytheon quickly moved into alloy junction transistor because of the lower noise, more rugged and lend it self to mass production, compared to point contact transistor.
• He is particularly known for developing the first mass-production alloy junction transistor and used the fallouts or transistors that did not meet specifications as transistors to be sold at a much lower cost, the CK721 and CK722.
• The "'2N107 "'is an early germanium alloy junction PNP transistor developed by General Electric ( GE ) in 1955, to become GE's entry into the electronic hobbyist market successfully started with the CK722 transistor.
• The first planar transistors had much worse characteristics than alloy junction transistors of the period, but as they could be mass-produced and alloy junction transistors could not, they cost much less and the characteristics of planar transistors improved very rapidly, quickly exceeding those of all earlier transistors and making earlier transistors obsolete.
