June 28, 2010... New C6 Series Provides MOSFETs for Greater Efficiency and Power Density

Irvine, California USA-- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog mixed-signal integrated circuits, high reliability semiconductors and RF subsystems, has expanded its CoolMOS™ product line with eight new high voltage superjunction MOSFETs designed for highest efficiency and power density.

Designated the C6 Series, the new 600V CoolMOS devices feature fifth-generation high voltage superjunction technology for extremely low conduction and switching losses, thus enabling the design of switching systems having new levels of efficiency and power density.

The new C6 Series MOSFETs are easy to design in. They are well suited for high power, high performance switch mode applications that include power factor correction, server and telecom power systems, solar inverters, arc welding, plasma cutting, battery chargers, medical, semiconductor capital equipment and induction heating.

"With energy efficiency a primary concern for next generation system designs, our new C6 devices enable CoolMOS ease-of-use, as well as performance advantages to reduce both switching and conduction losses over our previous C3 Series technologies," said Philip Zuk, Product Marketing Manager for the discrete Power Products Group. "We see this technology as being a leader in such markets as alternative energy."

Key Performance Features (typical values)

Ten percent lower on-resistance (Ron)
Forty three percent lower input capacitance (Ciss)
Forty five percent lower switching losses (Eoff) along with lower conduction losses
High body diode ruggedness
Ultra Low gate charge (Qg)
RoHS compliant
Note: Comparisons against comparable CoolMOS C3 Series devices
