AOL1240 40V N-Channel MOSFET General Description The AOL1240 uses trench MOSFET technology that is uniquely optimized to provide the most efficient high frequency switching performance.Power losses are minimized due to an extremely low combination of RDS(ON) and Crss.In addition,switching behavior is well controlled with a "Schottky style" soft recovery body diode.

The value of RθJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The Power dissipation PDSM is based on R θJA and the maximum allowed junction temperature of 150°C. The value in any given application depends on the user's specific board design, and the maximum temperature of 175°C may be used if the PCB allows it. B. The power dissipation PD is based on TJ(MAX)=175°C, using junction-to-case thermal resistance, and is more useful in setting the upper dissipation limit for cases where additional heatsinking is used. C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=175°C. Ratings are based on low frequency and duty cycles to keep initial TJ =25°C. D. The RθJA is the sum of the thermal impedance from junction to case RθJC and case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-case thermal impedance which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of TJ(MAX)=175°C. The SOA curve provides a single pulse rating. G. The maximum current rating is package limited. H. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. 2/6 www.freescale.net.cn AOL1240 40V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 120 10V 100 3.5V VDS=5V 4V 100 80 4.5V 80 ID(A) ID (A) 60 60 VGS=3V 125°C 40 40 25°C 20 20 0 0 0 1 2 3 4 1 5 6 3 4 5 Normalized On-Resistance 2 5 RDS(ON) (mΩ Ω) 2 VGS(Volts) Figure 2: Transfer Characteristics (Note E) VDS (Volts) Fig 1: On-Region Characteristics (Note E) 4 VGS=4.5V 3 2 VGS=10V 1 1.8 VGS=10V ID=20A 1.6 17 5 2 VGS=4.5V 10 1.4 1.2 ID=20A 1 0.8 0 0 5 0 10 15 20 25 30 ID (A) Figure 3: On-Resistance vs. Drain Current and Gate Voltage (Note E) 25 50 75 100 125 150 175 200 0 Temperature (°C) Figure 4: On-Resistance vs. Junction 18Temperature (Note E) 8 1.0E+02 ID=20A 1.0E+01 40 1.0E+00 125°C IS (A) RDS(ON) (mΩ Ω) 6 4 1.0E-02 25°C 1.0E-03 2 25°C 1.0E-04 1.0E-05 0 2 3/6 125°C 1.0E-01 4 6 8 10 VGS (Volts) Figure 5: On-Resistance vs. Gate-Source Voltage (Note E) 0.0 0.2 0.4 0.6 0.8 1.0 1.2 VSD (Volts) Figure 6: Body-Diode Characteristics (Note E) www.freescale.net.cn AOL1240 40V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 10 4500 VDS=20V ID=20A 4000 Ciss 3500 Capacitance (pF) VGS (Volts) 8 6 4 3000 2500 Coss 2000 1500 1000 2 Crss 500 0 0 0 5 10 15 20 25 30 35 Qg (nC) Figure 7: Gate-Charge Characteristics 40 45 0 10 15 20 25 30 35 VDS (Volts) Figure 8: Capacitance Characteristics 40 400 1000.0 RDS(ON) limited 10µs 350 100µs 300 1ms 10ms 250 10µs 10.0 DC 1.0 TJ(Max)=175°C TC=25°C Power (W) 100.0 ID (Amps) 5 TJ(Max)=175°C TC=25°C 17 5 2 10 200 150 100 0.1 50 0.0 0 0.01 0.1 1 VDS (Volts) 10 100 0.001 0.01 0.1 1 10 0 100 Pulse Width (s) 18Junction-to-Case Figure 10: Single Pulse Power Rating (Note F) Figure 9: Maximum Forward Biased Safe Operating Area (Note F) Zθ JC Normalized Transient Thermal Resistance 10 D=Ton/T TJ,PK=TC+PDM.ZθJC.RθJC In descending order D=0.5, 0.3, 0.1, 0.05, 0.02, 0.01, single pulse 40 RθJC=1.2°C/W 1 PD 0.1 Ton Single Pulse T 0.01 1E-05 0.0001 0.001 0.01 0.1 1 10 100 Pulse Width (s) Figure 11: Normalized Maximum Transient Thermal Impedance (Note F) 4/6 www.freescale.net.cn AOL1240 40V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 140 TA=25°C 120 TA=100°C Power Dissipation (W) IAR (A) Peak Avalanche Current 1000 100 100 TA=150°C TA=125°C 10 80 60 40 20 1 0 1 10 100 Time in avalanche, tA (µ µs) Figure 12: Single Pulse Avalanche capability (Note C) 1000 0 25 75 100 125 150 TCASE (°C) Figure 13: Power De-rating (Note F) 80 10000 60 1000 50 175 Power (W) Current rating ID(A) TA=25°C 40 17 5 2 10 100 10 20 1 0 0 25 50 75 100 125 150 TCASE (°C) Figure 14: Current De-rating (Note F) 0.1 10 0 1000 18 Pulse Width (s) Figure 15: Single Pulse Power Rating Junction-toAmbient (Note H) 1E-05 175 0.001 Zθ JA Normalized Transient Thermal Resistance 10 D=Ton/T TJ,PK=TA+PDM.ZθJA.RθJA 1 In descending order D=0.5, 0.3, 0.1, 0.05, 0.02, 0.01, single pulse 40 RθJA=60°C/W 0.1 PD 0.01 Single Pulse Ton T 0.001 1E-05 0.0001 0.001 0.01 0.1 1 10 100 1000 Pulse Width (s) Figure 16: Normalized Maximum Transient Thermal Impedance (Note H) 5/6 www.freescale.net.cn AOL1240 40V N-Channel MOSFET Gate Charge Test Circuit & Waveform Vgs Qg 10V + + Vds VDC - Qgs Qgd VDC - DUT Vgs Ig Charge Resistive Switching Test Circuit & Waveforms RL Vds Vds 90% + Vdd DUT Vgs VDC - Rg 10% Vgs Vgs t d(on) tr t d(off) t on tf toff Unclamped Inductive Switching (UIS) Test Circuit & Waveforms L 2 E AR = 1/2 LIAR Vds BVDSS Vds Id + Vdd Vgs Vgs I AR VDC - Rg Id DUT Vgs Vgs Diode Recovery Test Circuit & Waveforms Q rr = - Idt Vds + DUT Vds Isd Vgs Ig 6/6 Vgs L Isd + Vdd t rr dI/dt I RM Vdd VDC - IF Vds www.freescale.net.cn
