The nomenclature of the semiconductor model of the international electronic Federation
- Release on :2017-12-19
Germany, France, Italy, Holland, Belgium and other European countries, as well as Hungary, Romania, Yugoslavia, Poland and other Eastern European countries, mostly adopt the International Federation of electronics semiconductor discrete device naming method. This method of naming is composed of four basic parts, and the symbols and meanings of each part are as follows:
Part one: the material used by the alphabet to indicate the use of the device. The A- device uses materials such as germanium, the band gap Eg=0.6~1.0eV B- devices using materials such as silicon and Eg=1.0~1.3eV C- devices using Eg>1.3eV materials such as gallium arsenide, D- devices using materials such as InSb Eg<0.6eV, E- device using composite material and light battery
The second part: the type and the main features of the device are expressed by letters. A- detection switch diode mixer, B- varactor, C- low frequency power transistor, D- low frequency power transistor, E- tunnel diodes, F- high frequency low power transistor, G- composite device and other devices, H- magneto diode and K- open magnetic circuit Holzer element, L- high frequency power transistor, M- Holzer in the closed magnetic circuit element, P- sensitive devices, Q- devices, R- small power thyristor, S- power switch, T- power thyristor, U- power switch tube, X- double diode, rectifier diode, zener diode Z- Y-.
The third part: the number, letter and number are used to express the registration number. Three digits - the registration number, one letter plus two digit number representing the general semiconductor device - the registration number of the dedicated semiconductor device. Chip Electronics Stores was founded in 2003, specializing in electronic components distribution. We can provide you with Switches parts on sale.
The fourth part: using letters to file the same type of device. A, B, C, D, E all - all said the same type of device for mark grading according to a parameter.
In addition to four basic parts, sometimes a suffix is added to distinguish or further classify. The common suffixes are as follows: Chip Electronics Stores has a wide unobstructed Integrated Circuits wholesales china.
1. the suffix of the voltage regulator model. The first part of the suffix is a letter, said the range of allowable error stable voltage, A, B, C, letter D, E said the allowable error is + 1%, + 2%, + 5%, + 10% and + 15% respectively; the second part is the suffix number, an integer representing the nominal voltage numerical stability; the third part is the suffix letter V, on behalf of the decimal point, after the letter V as digital voltage regulator tube nominal voltage stability small value.
The 2. rectifier diode suffix is a number, indicating the maximum reverse peak voltage of the device, the unit is volt.
The suffix of the 3. thyristor model is also a number, usually marked with the maximum reverse peak voltage and the voltage value that is smaller in the maximum reverse turn off voltage.
For example, BDX51- represents a NPN silicon low frequency high power triode, and AF239S- is a PNP germanium high frequency small power triode. If you want to get more information, please click Integrated Circuits wholesales USA.
