IRVINE, Calif., June 3, 2008 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, has expanded its portfolio of high power semiconductor devices with a new family of resonant mode combi insulated gate bi-polar transistors (IGBTs) and a new series of low VF ultra-soft recovery diodes.
The twelve new application specific combi IGBTs are designed for high power, high performance applications that implement zero voltage switching (ZVS) and zero current switching (ZCS) topologies that are used in resonant mode and phase shifted bridge switching. Their features include devices of 600V and 1200V input voltages, high speed switching and internal parallel free wheeling diodes to help reduce system conduction losses.
Typical applications are in welding, induction heating, telecommunications, and medical equipment with power levels of 5000 watts or less.
The new DL Series of eight Microsemi low VF ultra-soft recovery diodes are designed for applications that use output rectification and other resonant mode circuits, such as phase shifted bridge. Their ultra-soft recovery minimizes or eliminates the use of a snubber and minimizes EMI, while their low voltage forward reduces conduction loss. The 600V series includes singles, duals, and common cathode configurations.
"Our group's focus is to provide a wide range of semiconductor solutions for designers of high voltage, high power and high performance applications," said Russell Crecraft, General Manager, Power Products Group in Bend, Oregon. "In that light, we continuously monitor market opportunities for enhancing our portfolio, as represented by these new IGBT and diode products," he said.
Both the IGBT Combi family and DL diode series are available for immediate shipment. Technical information on Microsemi's entire line of power semiconductors is available on the Microsemi website, http://www.microsemi.com.
