FDZ293P P-Channel 2.5 V Specified PowerTrench® BGA MOSFET
General Description
Combining Fairchild’s advanced 2.5V specified PowerTrench process with state of the art BGA packaging, the FDZ293P minimizes both PCB space and rDS(on). This BGA MOSFET embodies a breakthrough in packaging technology which enables the device to combine excellent thermal transfer characteristics, high current handling capability, ultralow profile packaging, low gate charge, and low rDS(on).
Features
• –4.6 A, –20 V rDS(on) = 46 mΩ @ VGS = –4.5 V rDS(on) = 72 mΩ @ VGS = –2.5 V
• Occupies only 2.25 mm2 of PCB area. Less than 50% of the area of a SSOT-6 • Ultra-thin package: less than 0.85 mm height when mounted to PCB • Outstanding thermal transfer characteristics: 4 times better than SSOT-6 • Ultra-low Qg x rDS(on) figure-of-merit • High power and current handling capability.
