AAT7357
20V P-Channel Power MOSFET
General Description
The AAT7357 is a low threshold dual 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 superi-
or to that normally found in a TSSOP-8 footprint
has been squeezed into the footprint of a
TSOPJW-8 package.

1. Based on thermal dissipation from junction to ambient while mounted on a 1" x 1" PCB with optimized layout. A 5-second pulse on a
1" x 1" PCB approximates testing a device mounted on a large multi-layer PCB as in most applications. R_θJF + R_θFA = R_θJA where the
foot thermal reference is defined as the normal solder mounting surface of the device's leads. R_θJF is guaranteed by design; however,
R_θCA is determined by the PCB design. Actual maximum continuous current is limited by the application's design.
2. Pulse test: Pulse Width = 300µs.
