International Rectifier Introduces New Automotive HEXFET Power MOSFET Technology that Combines High Efficiency With Excellent Ruggedness.Technology Editors EL SEGUNDO El Segundo (ĕl sēgŭn`dō), industrial city (1990 pop. 15,223), Los Angeles co., S Calif., on Santa Monica Bay; inc. 1917. Its products include navigation and computer systems, aircraft parts, office machines, telephone apparatus, and , Calif.--(BUSINESS WIRE)--Dec. 3, 2002 International Rectifier International Rectifier Corp. (NYSE: IRF) is a manufacturer of power semiconductors (MOSFET, IGBT, diodes and thyristors), located in El Segundo, California, USA. It has a market capitalization of 2.48 billion USD and is listed on the S&P Midcap 400. , IR(R) (NYSE NYSE See: New York Stock Exchange :IRF IRF Interferon Regulatory Factor IRF International Religious Freedom IRF Institut for Rationel Farmakoterapi (German) IRF Inherited Rights Filter (Novell) IRF Inherited Rights Filter ), introduces a new automotive-specific, trench HEXFET HEXFET Hexagonal Field Effect Transistor (R) power MOSFET A Power MOSFET is a specific type of Metal Oxide Semiconductor Field-Effect Transistor (MOSFET) designed to handle large powers. Compared to the other power semiconductor devices (IGBT, Thyristor... technology with 15% lower device on-resistance per unit area than the best-competing technology and excellent avalanche capability. The new 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 technology offers an avalanche capability comparable to industry-leading planar technology and up to twice that of currently available trench products. "The IR trench process extends the benefits of trench technology to the harsh automotive environment without sacrificing avalanche ruggedness," said Tony Hendrix, Director, Automotive Components Business Development at International Rectifier. The first product using this new trench technology is the Q101-qualified, 40-volt IRF2804 MOSFET suitable for high power automotive applications such as 14V integrated starter alternators, 14V synchronous rectifier rectifier, component of an electric circuit used to change alternating current to direct current. Rectifiers are made in various forms, all operating on the principle that current passes through them freely in one direction but only slightly or not at all in the alternators, electrical power steering power steering n. A device driven by the engine of a vehicle that facilitates the turning of the steering wheel by the driver. power steering Noun systems, and brush- and brush-less DC motor controls. The IR trench MOSFET technology will be rapidly extended to the other voltages that can be found in automotive applications with 40-volt, 55-volt, 75-volt and 100-volt products. The new IRF2804 automotive trench MOSFET offers the industry-lowest on-resistance of 2.3 milliohms in the TO-220 package. In addition, the new IRF2804 has low gate charge per unit area, required for high frequency operation up to 100kHz. The high avalanche capability of IR's automotive trench MOSFETs allows a lower voltage-rated device to be used in an application. For example, a 40-volt MOSFET can be used instead of a 55-volt MOSFET, taking advantage of the intrinsic lower on-resistance, as long as device maximum junction temperature is not exceeded. IR's new automotive trench MOSFETs deliver silicon performance previously unachievable without utilizing a more expensive package, larger die or multiple dies in parallel. IR's automotive trench MOSFETs also include 10% lower on-resistance temperature coefficient than competitive devices, which is particularly important in automotive applications where the nominal operating temperatures usually exceed 125 degrees Celsius and peak junction temperatures may approach 175 degrees Celsius.
