AO3702 N-Channel Enhancement Mode Field Effect Transistor with Schottky Diode General Description The AO3702/L uses advanced trench technology to provide excellent RDS(ON), low gate charge. A Schottky diode is provided to facilitate the implementation of a bidirectional blocking switch, or for DC-DC conversion applications. AO3702 and AO3702L are electrically identical. -RoHs Complaint -AO3702L is Halogen Free Features VDS (V) = 20V ID = 3.5A (V GS = 4.5V) RDS(ON) < 62m (VGS = 4.5V) RDS(ON) < 70m (VGS = 2.5V) RDS(ON) < 85m (VGS = 1.8V) SCHOTTKY VDS (V) = 20V, I F = 1A, VF<0.5V@0.5A SOT-23-5 Top View G S A 1 2 3 5 4 D K G D K S A Absolute Maximum Ratings T A=25C unless otherwise noted Symbol Parameter VDS Drain-Source Voltage Gate-Source Voltage TA=25C Continuous Drain Current Pulsed Drain Current B A MOSFET 20 8 3.5 2.7 25 Schottky Units V V A VGS TA=70C ID IDM VKA TA=25C A Schottky reverse voltage Continuous Forward Current Pulsed Forward Current Power Dissipation Junction and Storage Temperature Range Parameter: Thermal Characteristics MOSFET t 10s Maximum Junction-to-Ambient A Maximum Junction-to-Ambient A Maximum Junction-to-Lead C Thermal Characteristics Schottky Maximum Junction-to-Ambient Maximum Junction-to-Ambient Maximum Junction-to-Lead C A A B TA=70C TA=25C TA=70C IF IFM PD TJ, TSTG Symbol RJA RJL RJA RJL 1.15 0.7 -55 to 150 Typ 80.3 117 43 153 173 103 20 1 0.5 10 0.66 0.42 -55 to 150 Max 110 150 80 190 220 140 V A W C Units C/W Steady-State Steady-State t 10s Steady-State Steady-State C/W Alpha & Omega Semiconductor, Ltd. www.aosmd.com AO3702 Electrical Characteristics (TJ=25C unless otherwise noted) Symbol Parameter Conditions ID=250A, VGS=0V VDS=20V, VGS=0V TJ=55C VDS=0V, VGS=8V VDS=VGS ID=250A VGS=4.5V, VDS=5V VGS=4.5V, ID=3.5A RDS(ON) Static Drain-Source On-Resistance TJ=125C VGS=2.5V, ID=3A VGS=1.8V, ID=2.5A gFS VSD IS Forward Transconductance VDS=5V, ID=2A IS=1A,VGS=0V Diode Forward Voltage Maximum Body-Diode Continuous Current 0.5 25 50 70 56 66 15 0.7 1 1.6 260 VGS=0V, VDS=10V, f=1MHz VGS=0V, VDS=0V, f=1MHz 48 27 3 2.9 VGS=4.5V, VDS=10V, ID=3.5A 0.4 0.6 2.5 VGS=4.5V, VDS=10V, RL=3, RGEN=6 IF=3.5A, dI/dt=100A/s 3.2 21 3 14 3.4 0.37 0.5 0.1 20 52 9.2 1.7 12 19 4.5 3.8 320 62 90 70 85 S V A pF pF pF nC nC nC ns ns ns ns ns nC V mA pF ns nC 0.68 Min 20 1 5 100 1 Typ Max Units V A nA V A m m STATIC PARAMETERS BVDSS Drain-Source Breakdown Voltage IDSS IGSS VGS(th) ID(ON) Zero Gate Voltage Drain Current Gate-Body leakage current Gate Threshold Voltage On state drain current DYNAMIC PARAMETERS Ciss Input Capacitance Coss Crss Rg Output Capacitance Reverse Transfer Capacitance Gate resistance SWITCHING PARAMETERS Qg Total Gate Charge Qgs Gate Source Charge Qgd tD(on) tr tD(off) tf trr Gate Drain Charge Turn-On DelayTime Turn-On Rise Time Turn-Off DelayTime Turn-Off Fall Time Body Diode Reverse Recovery Time Qrr Body Diode Reverse Recovery Charge IF=3.5A, dI/dt=100A/s SCHOTTKY PARAMETERS VF Forward Voltage Drop IF=0.5A Irm CT trr Qrr Maximum reverse leakage current Junction Capacitance Schottky Reverse Recovery Time Schottky Reverse Recovery Charge VR=16V VR=16V, TJ=125C VR=10V IF=1A, dI/dt=100A/s IF=1A, dI/dt=100A/s A: The value of R JA is measured with the device mounted on 1in 2 FR-4 board with 2oz. Copper, in a still air environment with T A =25C. The value in any given application depends on the user's specific board design. The current rating is based on the t 10s thermal resistance rating. B: Repetitive rating, pulse width limited by junction temperature. C. The R JA is the sum of the thermal impedence from junction to lead R JL and lead to ambient. D. The static characteristics in Figures 1 to 6 are obtained using <300 s pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in SOA curve provides a single pulse rating. Rev1:March 2008 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25C.
