Devices: Abroad. Analogues of the Fatherland. The book 2 is systematized in tabular form in the alphanumeric sequence data on the main electrical parameters and design execution on domestic bipolar and field transistors. Rectifiers and Restrictive Diodes , Posts and Blocks , Varikapas , Stabilitrons and Stabistors , thyristors, light emitting and infrared diodes, linear scales and numeric-letter indicators, Diode and Transistor Optopars , intended for use in special electronic equipment. These devices tend to have improved parameters and higher reliability compared to similar (by digital designation) appliances for home appliances. The book also presents original special-purpose devices that have no analogues among household appliances. According to the devices given in the book, the corresponding analogues are given. A convenient form of searching and perception of information about the devices of interest allows the user to appreciate the book he purchased. It will be useful to a wide range of specialists and amateurs involved in the development, operation and repair of electronic equipment.
