    Transistor Introduced To The World For The First Time In Bell Laboratories

    • 1. Transistor Introduced To The World For The First Time In Bell Laboratories Transistor Introduced To The World For The First Time In Bell Laboratories 23.12.1947
    • 2. Invention Of The Transistor Invention Of The Transistor
    • 3. Invention Of The Transistor The transistor is one of the most important inventions of the 20th century. The invention of the transistor was carried out in 1947 in Bell's research laboratories by a team of John Bardeen and Walter Brattain, led by William Shockley.
    • 4. Invention Of The Transistor This team was awarded the Nobel Prize for Physics in 1956 for their work on semiconductors and the invention of the transistor.
    • 5. What is the Transistor? What is the Transistor? The transistor is an electronic circuit element made of semiconductor material.
    • 6. What is the Transistor? Their main task is to raise the current. They also perform voltage and power upgrades according to their usage in the circuit.
    • 7. BJT Transistors BJT Transistors Bipolar Junction Transistor consists the letters of the words. There are also transistor types such as FET, UJT.
    • 8. BJT Transistors Transistors are two types, PNP and NPN. In PNP type, base negative emitter and collector are positive crystal structure. In NPN type, base positive, emitter, and collector negative crystal structure.
    • 9. NPN Type Transistors NPN Type Transistors The structure of the NPN type transistors consists of a P- type semiconductor base material between two N-type semiconductors. The layer between two N-type substances serves to control the electron transition.
    • 10. PNP Type Transistors PNP Type Transistors The structure of PNP-type transistors is also similar to NPN type transistors. The only difference is that N-type semiconductor material is placed between two semiconductor materials of type P.
    • 11. What is FET? What is FET? Field Effective Transistor is an element for changing the channel current and conductivity in semiconductor materials with the help of load carriers.
    • 12. What İs FET? The single-pole FET was found much earlier than the bipolar standard BJT transistors. FET is most commonly seen in MOSFET and CMOS technologies. Major varieties; • JFET: Junction-FET disconnects the door and the body with a reverse-bias p-n connection. • MOSFET
    • 13. What is FET? • FREDFET: (Fast Recovery Epitaxial Diode-FET) is a special type of FET and has fast recovery characteristics. • TFET: (Tunnel-FET) is a FET type of special production for band-band tunneling. • IGBT • OFET: (Organic-FET) is a special type of FET that uses organic semiconductor material.
    • 14. What is UJT Transistor? What is UJT Transistor? Unijunction Transistor, UJT for short; In the timing circuits, it is a kind of transistor used in pulse generators. UJT transistors are used to generate pulses for triggering in thyristor and Triac circuits.UJT transistors are used in oscillator circuits to obtain periodic triggers.
    • 15. Operating The Transistor Operating The Transistor A transistor consists of three feet. These feet are called E, B, and C feet. In order for a transistor to work, a certain voltage must be applied to the basin. This voltage is called VBE.
    • 16. Usage Areas of Transistors Usage Areas of Transistors Transistors are form the basis of today's electronics. They are used in switching and amplifying processes in electronic circuits.
