FDZ2553N
Monolithic Common Drain N-Channel 2.5V Specified PowerTrench
BGA MOSFET
General Description
Combining Fairchild's advanced 2.5V specified
PowerTrench process with state-of-the-art BGA
packaging, the FDZ2553N minimizes both PCB space
and R
DS(ON)
. This Monolithic Common Drain BGA
MOSFET embodies a breakthrough in packaging
technology which enables the device to combine
excellent thermal transfer characteristics, high current
handling capability, ultra-low profile packaging, low gate
charge, and low R
DS(ON)
.

Notes:
1.
R
JA
is determined with the device mounted on a 1 in 2 oz. copper pad on a 1.5 x 1.5 in. board of FR-4 material. The thermal resistance from the junction to
the circuit board side of the solder ball, R
JB
, is defined for reference. For R
JC
, the thermal reference point for the case is defined as the top surface of the
copper chip carrier. R
JC
and R
JB
are guaranteed by design while R
JA
is determined by the user's board design.
