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 value in any given application depends on the user's specific board design. B. The power dissipation PD is based on TJ(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance. C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep initialTJ=25°C. D. The RθJA is the sum of the thermal impedence from junction to lead RθJL and lead 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-ambient thermal impedence which is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse rating. 2/6 www.freescale.net.cn AO4886 100V Dual N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 20 20 10V VDS=5V 4.5V 15 3.5V ID(A) ID (A) 15 10 5 10 125°C 5 VGS=3V 25°C 0 0 0 1 2 3 4 5 0 VDS (Volts) Fig 1: On-Region Characteristics (Note E) 2 3 4 5 6 VGS(Volts) Figure 2: Transfer Characteristics (Note E) 2.8 90 VGS=4.5V 80 70 VGS=10V 60 Normalized On-Resistance 100 RDS(ON) (mΩ Ω) 1 2.4 VGS=10V ID=3A 2 17 5 VGS=4.5V ID=3A 2 10 1.6 1.2 0.8 50 0 0 5 10 15 20 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) 150 1.0E+02 ID=3A 1.0E+01 130 40 90 25°C 70 1.0E-01 1.0E-02 25°C 1.0E-03 1.0E-04 1.0E-05 50 2 6 8 10 VGS (Volts) Figure 5: On-Resistance vs. Gate-Source Voltage (Note E) 3/6 125°C 125°C 110 IS (A) RDS(ON) (mΩ Ω) 1.0E+00 4 0.0 0.2 0.4 0.6 0.8 1.0 VSD (Volts) Figure 6: Body-Diode Characteristics (Note E) www.freescale.net.cn AO4886 100V Dual N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 1200 10 1000 VDS=50V ID=3A Ciss Capacitance (pF) VGS (Volts) 8 6 4 2 800 600 400 200 0 Coss 0 0 5 10 15 Qg (nC) Figure 7: Gate-Charge Characteristics 0 20 100.0 100.0 20 40 60 80 VDS (Volts) Figure 8: Capacitance Characteristics 100 RDS(ON) limited TA=100°C 10.0 TA=25°C 10.0 TA=125°C 10µs ID (Amps) IAR (A) Peak Avalanche Current Crss 1.0 100µs 1ms TA=150°C 0.1 TJ(Max)=150°C TA=25°C 10ms 10s DC 0.0 1.0 1 0.1 10 100 1000 Time in avalanche, tA (µ µs) Figure 9: Single Pulse Avalanche capability (Note C) 1 10 100 VDS (Volts) Figure 10: Maximum Forward Biased Safe Operating Area (Note F) 10000 TA=25°C Power (W) 1000 100 10 1 1E-05 0.001 0.1 10 1000 Pulse Width (s) Figure 11: Single Pulse Power Rating Junction-to-Ambient (Note F) 4/6 www.freescale.net.cn AO4886 100V Dual N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 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 RθJA=90°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 12: Normalized Maximum Transient Thermal Impedance (Note F) 5/6 www.freescale.net.cn AO4886 100V Dual 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
