The electronic devices such as portable communications, video equipment and computing devices are challenging the semiconductor industry to design, develop and manufacture the small electronic components. The signal diodes are the nonlinear semiconductor devices used in electronics circuits where high frequencies or small current is required. They are made to carry upto several KA of current when forward biased and are bale to block the KV when reverse biased. Signal diodes are also called as point contact diode, switching diode and glass passivated diode and are smaller is size as compared to other types of diodes. The signal diode is enclosed in a glass like structure to protect the PN junction. The signal diode has red and black color band at one end of the diode to identify the cathode terminal. The small signal diodes are characterized by the low power and current ratings. These signal diodes have various applications in digital communications and signal processing. Signal diodes are used in snubbing circuits, switching operations, high speed data lines and other I/O parallel connected ports. To overcome the space requirement on the digital circuit boards, the signal diodes are connected in parallel mode creating array known as small signal diode arrays. The signal diodes are enclosed in single line or double line package that features from around 4 to 14 diodes and offers common anode and cathode configurations.
The major driver that supports the global signal diode market is the compact size of the diode and the ease of manufacturing of the diodes. The other parameters that support the growth of the signal diode market are low forward and reverse resistance, and low junction capacitance. The major restraining factor that restricts the growth of the signal diode market is the high electrical noise and low breakdown voltage. However, the manufacturers of the compact electronic devices faces the restrictions of the board space, thus giving rise to the requirement of the packaging technology, boosting towards the growth of the signal diode market.
The global signal diode market is segmented into material type, mounting type, end use industry, and geography. On the basis of material type, the signal diode market is segmented into germanium and silicon. In terms of mounting type, the global signal diode market is classified into wire ended and surface mount. Based on end use industry the global signal diode market is segmented into consumer electronics, aerospace and defense, telecommunication devices, automotive and others. Geographically, global signal diode market can be segmented into North America, Europe, Middle East & Africa, Asia Pacific and Latin America. North America is expected to be the leading market for the signal diode market in terms of revenue in the coming years. This is due to the already developed technology advancement in the North America. Asia Pacific region is anticipated as an emerging market for the signal diode due to presence of large number of the semiconductor companies and the emerging economies such as China, India and Japan.
Some of the key players operating in the global signal diode market are ON Semiconductor, STMicroelectronics, Vishay Intertechnology, Inc., Bourns Inc., Diodes Incorporated, Infineon Technologies, Microsemi Corporation, KEC Holdings, and Toshiba Corporation among others.
