CISSOID just released CHT-GANYMEDE, a high-temperature 80V dual series small-signal diode in a small hermetically sealed metal can TO-18 package. This new device includes two diodes connected in series that can sustain a reverse voltage of 80V, have a maximum forward current of 300mA at 225°C and are suitable for operation from -55°C up to +225°C. This dual diode is a general purpose discrete component which and can be used in a variety of app...

Six new PowerWise® reference designs from National Semiconductor Corp. empower design engineers to speed through the design process, delivering products that consume less power, extend battery life and generate less heat. PowerWise reference designs combine energy-efficient devices and arrange them in a system to actively lower power consumption and reduce heat dissipation.

National Semiconductor has introduced a constant-current controller that enables off-line, uniform, flicker-free dimming of high-brightness light-emitting diodes (LEDs) with a conventional TRIode for Alternating Current (TRIAC) forward or reverse phase-control wall dimmer. The LM3445 TRIAC dimmable LED driver enables a full 100:1 range of dimming capability and can maintain greater than 1A of constant current to large strings of LEDs in a variet...

National Semiconductor today marked the 20-year anniversary of its SIMPLE SWITCHER brand of products. Since 1990, electronic system engineers around the world have created designs featuring National’s SIMPLE SWITCHER products, with over 1.5 billion units shipped to date. More than 100,000 engineers design power supplies with SIMPLE SWITCHER power modules, voltage regulators and controllers each year, with end applications spanning the entire e...

Hitachi Europe Ltd, Power Devices Division (PDD) will exhibit its leading-edge IGBT technology and the latest power semiconductors modules at PCIM 2009 which is being held from May 12th to May 14th 2009 at the Exhibition Centre Nuremburg, Germany.

ROHM Semiconductor has introduced a new series of CMOS LDO regulators featuring ROHM’s proprietary automatic power-saving (APS) function that dynamically switches performance characteristics based on operating conditions. The BHxxPB1 Series combines the benefits of LDOs — small packaging, minimal external components and simple design process — with very low average power consumption.

ROHM Semiconductor has announced the industry’s first mass production of SiC power modules (1200V/100A rated) entirely consisting of SiC power elements and enabling high frequency operation above 100kHz. Thus, the company is now able to offer industry-leading SiC devices such as Schottky barrier diodes and MOSFETs as well as a complete SiC module solution.

ROHM has revealed the development of a 2nd generation high-voltage (1200V) SiC power MOSFET designed for inverters and converters in power conditioners for industrial devices and photovoltaic power generation. Features include low power loss and high reliability, reducing power consumption and enabling support for smaller peripheral components.

ROHM Semiconductor will present its latest products and technologies at PCIM, the leading trade fair for power electronics in Nuremberg, from May 8 to 10 (Hall 12, Booth 601). Based on the most recent developments in the R/D centers of ROHM and LAPIS and the expertise in the design and manufacturing of state-of-the-art power management, the products address the increasing demand for more energy efficiency, miniaturization, reliability, reduced c...

Diodes Incorporated has announced a miniature current monitor delivering what it says is the world’s smallest solution size for battery current measurement in portable applications. Packaged in the thin 4-pin 1.2mm x 1.8mm DFN package, the ZXCT1023 will support system management functions aimed at extending active run times.
