December 11, 2009 (FinancialWire) — Microsemi Corp. (NASDAQ: MSCC), a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has introduced a new line of linear MOSFET power modules for applications ranging from factory automation to electric vehicles and industrial power supplies.

The line includes 10 modules available in 100V, 200V, 500V, 600V and 1000V voltages, with a choice of single or dual switch configurations in SP1 or SP3 low profile high performance packages. The SP1 package includes a single MOSFET switch with a series shunt resistor to accurately control the current in the switch, as well as a positive temperature coefficient thermistor to monitor the module’s base plate temperature, for adjusting its power dissipation.

The SP3 package incorporates two identical cells compared to the SP1 design for additional integration. Dual switch integration allows designers to minimize the number of modules required when many cells are required in parallel for high power applications. Both the SP1 and SP3 modules use ALN substrates to achieve the highest possible power density.

Modules may be connected in series for voltage operation higher than 1000V. A matrix comprised of multiple linear cells connected in series and in parallel can be used to drive high voltage and high power loads.
