Founded in 1948, the Electronic Industries Association of Japan (EIAJ) was one of two Japanese electronics trade organizations that were merged into the Japan Electronics and Information Technology Industries Association (JEITA).


Prior to the merger, EIAJ created a number of electronics industry standards that have had some use outside Japan, including:

Another standard is the multi-channel TV sound system used with the NTSC-J analog TV system. It is often referred to simply as EIAJ, or sometimes as FM-FM audio.

Transistor nomenclature

The Japanese technical standard JIS-C-7102 provides a method of developing part numbers for transistor devices. [1] The part number has up to five fields, for example in the number 2SC82DA:


in 1948, Electronic Industries Association of Japan has first appeared in [Taito, Tokyo|Taito]], Tokyo, Japan. in 2000, Electronic Industries Association of Japan became a Pending merger with JEIDA and was Reorganized into JEITA.

Insulated-gate bipolar transistor Type of solid state switch

An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P-N-P-N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure without regenerative action. Although the structure of the IGBT is topologically the same as a thyristor with a 'MOS' gate, the thyristor action is completely suppressed and only the transistor action is permitted in the entire device operation range. It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs), electric cars, trains, variable speed refrigerators, lamp ballasts, arc-welding machines, and air conditioners.

Thyristor Type of solid state switch

A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed. There are two designs, differing in what triggers the conducting state. In a three-lead thyristor, a small current on its Gate lead controls the larger current of the Anode to Cathode path. In a two-lead thyristor, conduction begins when the potential difference between the Anode and Cathode themselves is sufficiently large.

A TRIAC is a three terminal electronic component that conducts current in either direction when triggered. The term TRIAC is a genericised trademark.

The Japan Electronics and Information Technology Industries Association is a Japanese trade organization for the electronics and IT industries. It was formed in 2000 from two earlier organizations, the Electronic Industries Association of Japan and the Japan Electronic Industries Development Association.

Push–pull output

A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance both the load capacity and switching speed.

D-Terminal Analog video connector used in Japan

A D-Terminal or D-tanshi (D端子) is a type of analog video connector found on Japanese consumer electronics, typically HDTV, DVD, Blu-ray, D-VHS and HD DVD devices. It was developed by the EIAJ in its standard, RC-5237, for use in digital satellite broadcast tuners. In appearance it is a small flat trapezic connector, the same connector as the AAUI connector used by Apple Computer for some time to connect to ethernet.

IC power-supply pin

Almost all integrated circuits (ICs) have at least two pins that connect to the power rails of the circuit in which they are installed. These are known as the power-supply pins. However, the labeling of the pins varies by IC family and manufacturer.

Electronic component

An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components.

TO-92 Small and cheap semiconductor package often used for transistors

The TO-92 is a widely used style of semiconductor package mainly used for transistors. The case is often made of epoxy or plastic, and offers compact size at a very low cost.

EIAJ connector Type of coaxial power connector

The EIAJ connector type, more formally known as EIAJ RC-5320A, is a type of coaxial power connector or jack for small appliances.

Electronic symbol

An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering discipline, based on traditional conventions.


The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. Its numbering follows the JEDEC standard. It is a transistor type of enduring popularity.

The Japan Electronic Industry Development Association was an industry research, development, and standards body for electronics in Japan. It was merged with EIAJ to form JEITA on November 1, 2000.

Jun-ichi Nishizawa was a Japanese engineer and inventor. He is known for his electronic inventions since the 1950s, including the PIN diode, static induction transistor, static induction thyristor, semiconductor laser, SIT/SITh, and fiber-optic communication. His inventions contributed to the development of internet technology and the information age.

Coaxial power connector

A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes.


The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. It is notably often the first type of bipolar transistor hobbyists encounter and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required. The BC548 is low in cost and widely available.

TOSLINK Standardized optical fiber connector system

TOSLINK is a standardized optical fiber connector system. Also known generically as optical audio, its most common use is in consumer audio equipment, where it carries a digital audio stream from components such as CD and DVD players, DAT recorders, computers, and modern video game consoles, to an AV receiver that can decode two channels of uncompressed lossless PCM audio or compressed 5.1/7.1 surround sound such as Dolby Digital or DTS Surround System. Unlike HDMI, TOSLINK does not have the bandwidth to carry the lossless versions of Dolby TrueHD, DTS-HD Master Audio, or more than two channels of PCM audio.


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. Like the CK722, it enjoyed a long-standing popularity. General Electric decided to designate it with a JEDEC 2N- series identification. This is unusual for a hobby device. Soon after, other manufacturers got involved in the hobby business like Sylvania, Tung-Sol and RCA.
