MOSFET-Schottky Chip Permits Double-Sided Cooling

30-V monolithic power MOSFET and Schottky diode in the PolarPAK package allows both top and bottom-side cooling

Oct. 8, 2008

From Vishay Intertechnology comes a 30-V monolithic power MOSFET and Schottky diode in the PolarPAK package, which allows both top and bottom-side cooling in systems with forced air cooling. The SiE726DF offers an on-resistance of 0.0024 Ω max at a 10-V gate drive, and can handle current levels 50% higher than the SO-8 in the same footprint size without a heatsink.
