International Rectifier Introduces TO-220 Synchronous Rectification MOSFETs that Shrink Part Count by 30% or More.EL SEGUNDO, Calif. -- International Rectifier, 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 ), a world leader in power management technology, today introduced very high efficiency 75V and 100V HEXFET HEXFET Hexagonal Field Effect Transistor (r) power MOSFETs in the TO-220 package that enable a part count reduction of 30% or more in secondary synchronous rectification, full-bridge topology power supplies compared to competing devices in the same package. The new 75V MOSFETs are designed to shrink circuit size and increase power density in high power server AC-DC switch-mode power supplies (SMPS SMPS Society for Marketing Professional Services SMPS Switching Mode Power Supply SMPS Switched Mode Power Supply ) with 12V output or in 48V rail ORing circuits. The new 100V devices suit high power flyback The term “flyback” may refer to
"As the demand for ever-faster data processing continues to increase, information processing systems demand more power. In spite of this, system form factors must remain the same or even shrink. The new 75 and 100V TO-220 HEXFET MOSFETs allow more power management to fit in the same amount of space, and have the lowest device on-resistance among competing MOSFETs," said Stephen Oliver, marketing manager for SMPS Products at International Rectifier. The IRFB IRFB International Rugby Football Board (Ireland) 3077PbF is a 75V 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 with 3.3mOhm maximum device on-resistance, and enables a 30% parts count reduction (from ten TO-220 devices to seven TO-220 devices), with a reduced PCB PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. area and heatsinking for higher power density in 3kW server SMPS with 12V output. The IRFB4110PbF is a 100V MOSFET with 4.0mOhm maximum device on-resistance, and can slash component count in half, reducing PCB area and reducing heat sink size. More information is posted on the International Rectifier Web site: http://www.irf.com/whats-new/nr051215.html Pricing and Availability Pricing for the IRFB4110PbF (100V) is US $2.28 each, while the IRFB3077PbF (75V) is US $1.99 each, both in 10,000-unit quantity. The new synchronous HEXFET MOSFETs are available now. Prices are subject to change. The devices are lead-free (PbF) and are RoHS-compliant.
