Polar3™ Standard Power MOSFETs are suitable for a wide variety of power switching systems, including high-voltage power supplies, capacitor discharge circuits, pulse circuits, laser and x-ray generation systems, high-voltage automated test equipment, and energy tapping applications from the power grid.

Due to the positive temperature coefficient of their on-state resistance, these high-voltage Power MOSFETs can be operated in parallel, thereby eliminating the need for lower voltage, series-connected devices and enabling cost-effective power systems. Other benefits include component reduction in gate drive circuitry, simpler design, improved reliability, and PCB space saving.
