P-Channel 1.5 V Specified PowerTrench^® Thin WL-CSP MOSFET
-20 V, -3.7 A, 75 mΩ
Features
„ Max r_DS(on) = 75 mΩ at V_GS = -4.5 V, I_D = -2.0 A
„ Max r_DS(on) = 90 mΩ at V_GS = -2.5 V, I_D = -1.5 A
„ Max r_DS(on) = 110 mΩ at V_GS = -1.8 V, I_D = -1.0 A
„ Max r_DS(on) = 150 mΩ at V_GS = -1.5 V, I_D = -1.0 A
„ Occupies only 1.0 mm² of PCB area.Less than 30% of the
area of 2 x 2 BGA
„ Ultra-thin package: less than 0.4 mm height when mounted to
PCB
„ HBM ESD protection level >4.4kV typical (Note 3)
„ RoHS Compliant
General Description
Designed on Fairchild's advanced 1.5 V PowerTrench^® process
with state of the art "fine pitch" Thin WLCSP packaging process,
the FDZ371PZ minimizes both PCB space and r_DS(on). This
advanced WLCSP MOSFET embodies a breakthrough in
packaging technology which enables the device to combine
excellent thermal transfer characteristics, ultra-low profile
packaging, low gate charge, and low r_DS(on).
