AAT8543
20V P-Channel Power MOSFET General Description
The AAT8543 is a low threshold P-channel MOSFET designed for the battery, cell phone, and PDA markets. Using AnalogicTech's ultra-high-density MOSFET process and space-saving, small-outline, J-lead package, performance superior to that normally found in a TSOP-6 footprint has been squeezed into the footprint of an SC70JW-8 package.
