Alpha and Omega Semiconductor Releases SRFET(TM) Series of MOSFETs With Monolithically Integrated Schottky Diode.SUNNYVALE, Calif. -- Alpha and Omega alpha and omega n. 1. The first and the last: "I am Alpha and Omega, the beginning and the ending, saith the Lord" Revelation 1:8. 2. The most important part. Semiconductor, Inc. (AOS (Alternative Operator Services) Operator services provided by a third-party organization. See operator services. 1. AOS - /aws/ (East Coast), /ay-os/ (West Coast) A PDP-10 instruction that took any memory location and added 1 to it. ), a leading developer of advanced power semiconductor solutions, announced today that it has released a brand new family of power MOSFETs that feature an integrated Schottky diode The Schottky diode (named after German physicist Walter H. Schottky; also known as hot carrier diode) is a semiconductor diode with a low forward voltage drop and a very fast switching action. . The SRFET(TM) family of MOSFETs is targeted for applications such as notebook and desktop PCs, servers, graphics cards, gaming consoles, and for general purpose point-of-load dc/dc converter applications. AOS developed the Soft Recovery MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged , or SRFET(TM), to help designers improve the efficiency and switching performance of their dc/dc converters. Standard MOSFETs include a poor performing parasitic diode that typically has a high forward voltage drop Noun 1. voltage drop - a decrease in voltage along a conductor through which current is flowing free fall, drop, dip, fall - a sudden sharp decrease in some quantity; "a drop of 57 points on the Dow Jones index"; "there was a drop in pressure in the pulmonary of 0.7V. The SRFET(TM) features a monolithically integrated Schottky diode, with a forward voltage of only 0.4V, thereby reducing the diode's conduction loss by over 40%, and improving overall system efficiency. Another benefit of the SRFET(TM) is that its internal Schottky diode reduces the diode reverse-recovery current that is experienced with standard MOSFETs. Monolithic integration overcomes the problem that co-packaged Schottky diodes have with wiring inductance that renders them ineffective at high switching speeds. The result is up to 30% less ringing as well as less power loss due to synchronous MOSFET shoot-through. On-resistance performance is not sacrificed, as demonstrated with the AOL (A division of Time Warner, Inc., New York, NY, www.aol.com) The world's largest online information service with access to the Internet, e-mail, chat rooms and a variety of databases and services. 1412, which features a low 3.9mOhm maximum RDS (1) (Remote Data Services) A set of programming interfaces from Microsoft that enables users to update data on the Internet or intranets from their ActiveX-enabled browser. (ON) rating. The SRFET(TM) combination of excellent switching performance and low RDS(ON) allows designers to increase the efficiency and switching frequency of their dc/dc converter circuits. Pricing and Availability: The AOL1412, AO4458, and AO4932 are now available in bottom-exposed UltraSO-8(TM), single SO-8, and dual SO-8, respectively. Samples are available from stock with production quantities available in 8 weeks. Pricing starts at $0.96, $0.87, and $0.92 for 1,000 units, respectively. About AOS: Alpha and Omega Semiconductor Inc is a fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips.
