AON7446 60V N-Channel MOSFET TM SDMOS General Description Product Summary TM V 60V DS The AON7446 is fabricated with SDMOS trench I (at V =10V) 8A technology that combines excellent R with low gate DS(ON) D GS charge and low Qrr.The result is outstanding efficiency R (at V =10V) < 145m DS(ON) GS with controlled switching behavior. This universal R (at V = 7V) < 160m DS(ON) GS technology is well suited for PWM, load switching and general purpose applications. 100% UIS Tested 100% R Tested g DFN 3x3 EP D Top View Bottom View Top View 1 8 2 7 3 6 4 G 5 Pin 1 S Absolute Maximum Ratings T =25C unless otherwise noted A Parameter Symbol Maximum Units Drain-Source Voltage V 60 V DS Gate-Source Voltage V 20 V GS T =25C 8 C Continuous Drain I D Current T =100C 5 A C C Pulsed Drain Current I 17 DM T =25C 3.3 A Continuous Drain I A DSM Current T =70C 2.7 A C Avalanche Current I , I 10 A AS AR C Avalanche energy L=0.1mH E , E 5 mJ AS AR T =25C 16.7 C P W D B Power Dissipation T =100C 7 C T =25C 3.1 A P W DSM A T =70C Power Dissipation 2 A Junction and Storage Temperature Range T , T -55 to 150 C J STG Thermal Characteristics Parameter Symbol Typ Max Units A t 10s Maximum Junction-to-Ambient 30 40 C/W R JA A D Steady-State Maximum Junction-to-Ambient 60 75 C/W Maximum Junction-to-Case Steady-State R 6.2 7.5 C/W JC Rev 1: Mar. 2011 www.aosmd.com Page 1 of 7 AON7446 Electrical Characteristics (T =25C unless otherwise noted) J Symbol Parameter Conditions Min Typ Max Units STATIC PARAMETERS BV Drain-Source Breakdown Voltage I =250A, V =0V 60 V DSS D GS V =60V, V =0V 10 DS GS I Zero Gate Voltage Drain Current A DSS T =55C 50 J I Gate-Body leakage current V =0V, V = 20V 100 nA DS GS GSS V V =V I =250A 2.2 2.7 3.3 V Gate Threshold Voltage GS(th) DS GS D V =10V, V =5V I On state drain current 17 A D(ON) GS DS V =10V, I =3A 113 145 GS D m R Static Drain-Source On-Resistance T =125C 197 237 DS(ON) J V =7V, I =2.5A 118 160 m GS D V =5V, I =3A g Forward Transconductance 7.5 S DS D FS V Diode Forward Voltage I =1A,V =0V 0.76 1 V S GS SD I Maximum Body-Diode Continuous Current 15 A S DYNAMIC PARAMETERS C Input Capacitance 190 237 285 pF iss V =0V, V =30V, f=1MHz C Output Capacitance 17 25 33 pF GS DS oss C Reverse Transfer Capacitance 5 9 13 pF rss V =0V, V =0V, f=1MHz R Gate resistance 0.7 1.4 2.1 GS DS g SWITCHING PARAMETERS Q Total Gate Charge 3.5 4.4 5.3 nC g V =10V, V =30V, I =3A Q Gate Source Charge 0.7 0.9 1.1 nC gs GS DS D Q Gate Drain Charge 0.7 1.1 1.6 nC gd t Turn-On DelayTime 4.5 ns D(on) t Turn-On Rise Time V =10V, V =30V, R =10, 1.5 ns r GS DS L R =3 t Turn-Off DelayTime 15 ns D(off) GEN t Turn-Off Fall Time 1.5 ns f t I =3A, dI/dt=500A/s rr Body Diode Reverse Recovery Time F 5.4 7.7 10 ns Q I =3A, dI/dt=500A/s nC rr Body Diode Reverse Recovery Charge F 9 13 17 2 A. The value of R is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air environment with T =25C. The JA A Power dissipation P is based on R t 10s value and the maximum allowed junction temperature of 150C. The value in any given DSM JA application depends on the user s specific board design, and the maximum temperature of 150C may be u sed if the PCB allows it. B. The power dissipation P is based on T =150C, using junction-to-case thermal resistance, and is more useful in setting the upper D J(MAX) dissipation limit for cases where additional heatsinking is used. C. Repetitive rating, pulse width limited by junction temperature T =150C. Ratings are based on low frequency and duty cycles to keep J(MAX) initial T =25C. J D. The R is the sum of the thermal impedence from junction to case R and case to ambient. JA JC E. The static characteristics in Figures 1 to 6 are obtained using <300s pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T =150C. The SOA curve provides a single pulse ratin g. J(MAX) 2 G. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with T =25C.
