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. RJF + RFA = RJA where the foot thermal reference is defined as the normal solder mounting surface of the device's leads. RJF is guaranteed by design, however RCA is determined by the PCB design. Actual maximum continuous current is limited by the application's design. Note 2: Pulse test: Pulse Width = 300 s Note 3: Guaranteed by design. Not subject to production testing. 2 7128.2002.11.0.6 AAT7128 30V N-Channel Power MOSFET Typical Characteristics (TJ = 25C unless otherwise noted) Output Characteristics 24 Transfer Characteristics 10V 6V 24 4.5V 5V 18 18 4V 125C ID (A) IDS (A) -55C 25C 12 3.5V 12 6 6 3V 0 0 0 0 0.5 1 1.5 2 2.5 1 2 3 3 4 5 6 VGS (V) VDS (V) On-Resistance vs. Gate to Source Voltage On-Resistance vs. Drain Current 120 75 ID = 4.8A VGS = 4.5V 100 RDS(ON) (m) RDS(ON) (m) 60 45 VGS = 10V 30 15 80 60 40 20 0 0 0 4 8 12 16 20 0 24 2 4 ID (A) Gate Charge 10 10 100 TJ = 150C 10 6 IS (A) VGS (V) 8 Source-Drain Diode Forward Voltage VD=15V ID=4.8A 8 6 VGS (V) 4 TJ = 25C 1 2 0 0.1 0 2 4 6 QG, Charge (nC) 7128.2002.11.0.6 8 10 0 0.2 0.4 0.6 0.8 1 1.2 1.4 VSD (V) 3 AAT7128 30V N-Channel Power MOSFET Ordering Information Package Marking SOP-8 7128 Part Number Bulk Tape and Reel N/A AAT7128IAS-T1 Package Information 6.00 0.20 3.90 0.10 SOP-8 4.90 0.10 0.42 0.09 x 8 1.27 BSC 45 4 4 0.175 0.075 1.55 0.20 0.375 0.125 0.235 0.045 0.825 0.445 Advanced Analogic Technologies, Inc. 830 E.
