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 impedance from junction to lead RθJL and lead to ambient. E. The static characteristics in Figures 1 to 6 are obtained using or equal to 4.5V Figure 9: Maximum Forward Biased Safe Operating Area (Note F) Figure 10: Single Pulse Power Rating Junction-toAmbient (Note F) Zθ JA Normalized Transient Thermal Resistance 10 In descending order D=0.5, 0.3, 0.1, 0.05, 0.02, 0.01, single pulse D=Ton/T TJ,PK=TA+PDM.ZθJA.RθJA 1 RθJA=75°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 11: Normalized Maximum Transient Thermal Impedance (Note F) Rev.1.0: August 2013 www.aosmd.com Page 4 of 5 AO4578 Gate Charge Test Circuit & Waveform Vgs Qg 10V + + Vds VDC - Qgs Qgd VDC DUT - Vgs Ig Charge R es istiv e S w itch ing T e st C ircu it & W a ve fo rm s RL V ds Vds DUT Vgs 90 % + Vdd VDC - Rg 1 0% Vgs V gs t d (o n ) tr t d (o ff) to n tf t o ff D iode R ecovery T est C ircuit & W aveform s Q rr = - V ds + Idt DUT V gs V ds - Isd V gs Ig Rev.1.0: August 2013 L Isd + VD C - IF t rr dI/dt I RM V dd V dd V ds www.aosmd.com Page 5 of 5
