Chapter 16 & 17: Other Two-Terminal Devices & pnpn and Other Devices Chapter 16: Other Two-Terminal Devices There are a number of two-terminal devices having a single p–n junction like the semiconductor or Zener diode but with different modes of operation, terminal characteristics, and areas of application. A number, including the Schottky, tunnel, varactor, photodiode, and solar cell, will be introduced in this chapter. In addition, two-terminal devices of a different construction, such as the photoconductive cell, LCD (liquid-crystal display), and thermistor, will be examined. |
Chapter 17: pnpn and Other Devices Chapter 17: pnpn and Other Devices In Chapter 17, a number of important devices not discussed in detail in earlier chapters are introduced. The two-layer semiconductor diode has led to three-, four-, and even five-layer devices. A family of four-layer pnpn devices will first be considered: the SCR (silicon-controlled rectifier), the SCS (silicon-controlled switch), the GTO (gate turn-off switch), the LASCR (light-activated SCR), and then an increasingly important device—the UJT (unijunction transistor). Those four-layer devices with a control mechanism are commonly referred to as thyristors, although the term is most frequently applied to the SCR. The chapter closes with an introduction to the phototransistor, opto-isolators, and the PUT (programmable unijunction transistor). |
Re: Chapter 17: pnpn and Other Devices How short these chapters are?:agasp_::agasp_: brother... Abh yoon tay na kroo |
Re: Chapter 17: pnpn and Other Devices Chapter 16 & 17, Short hain, These are Introduction to Chapters. Chalain theek ha. |
