AO4312 36V N-Channel MOSFET General Description The AO4312 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 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 AO4312 36V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 100 100 4V 10V 4.5V VDS=5V 3.5V 80 80 60 ID(A) ID (A) 60 3V 40 40 20 125°C 25°C 20 VGS=2.5V 0 0 0 1 2 3 4 0 5 18 VGS=4.5V 12 10 8 VGS=10V 6 4 2 Normalized On-Resistance RDS(ON) (mΩ Ω) 14 3 4 5 6 1.8 VGS=10V ID=20A 1.6 17 5 2 10 =4.5V 1.4 1.2 VGS 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) 12 1.0E+02 ID=20A 1.0E+01 40 9 1.0E+00 125°C 6 IS (A) RDS(ON) (mΩ Ω) 2 2 16 125°C 1.0E-01 1.0E-02 25°C 1.0E-03 3 25°C 1.0E-04 1.0E-05 0 2 6 8 10 VGS (Volts) Figure 5: On-Resistance vs. Gate-Source Voltage (Note E) 3/6 1 VGS(Volts) Figure 2: Transfer Characteristics (Note E) VDS (Volts) Fig 1: On-Region Characteristics (Note E) 4 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 AO4312 36V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS 10 2800 VDS=18V ID=20A 2400 Ciss Capacitance (pF) VGS (Volts) 8 6 4 2000 1600 1200 Coss 800 2 400 0 0 0 5 10 15 20 25 Qg (nC) Figure 7: Gate-Charge Characteristics 30 0 1000.0 IAR (A) Peak Avalanche Current Crss 6 12 18 24 30 VDS (Volts) Figure 8: Capacitance Characteristics 36 1000.0 TA=25°C 10µs TA=100°C 100.0 ID (Amps) 100.0 TA=150°C 100µs RDS(ON) limited 10.0 1ms 10ms 1.0 100ms TA=125°C 10.0 TJ(Max)=150°C TA=25°C 0.1 10s DC 0.0 1.0 1 0.01 10 100 1000 Time in avalanche, tA (µ µs) Figure 12: Single Pulse Avalanche capability (Note C) 0.1 1 VDS (Volts) 10 100 Figure 10: Maximum Forward Biased Safe Operating Area (Note F) 10000 TA=25°C Power (W) 1000 100 10 1 0.00001 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 AO4312 36V N-Channel MOSFET TYPICAL ELECTRICAL AND THERMAL CHARACTERISTICS Zθ JA Normalized Transient Thermal Resistance 10 1 D=Ton/T TJ,PK=TA+PDM.ZθJA.RθJA In descending order D=0.5, 0.3, 0.1, 0.05, 0.02, 0.01, single pulse RθJA=60°C/W 0.1 PD 0.01 Single Pulse Ton T 0.001 0.00001 0.0001 0.001 0.01 0.1 1 10 100 1000 Pulse Width (s) Figure 12: Normalized Maximum Transient Thermal Impedance (Note F) 4 5/6 www.freescale.net.cn AO4312 36V 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
