| FDS4070N3 May 2003 FDS4070N3 40V N-Channel PowerTrench MOSFET General Description This N-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for "low side" synchronous rectifier operation, providing an extremely low RDS(ON) in a small package. Features * 15.3 A, 40 V. RDS(ON) = 7.5 m @ VGS = 10 V * High performance trench technology for extremely low RDS(ON) * High power and current handling capability * Fast switching, low gate charge * FLMP SO-8 package: Enhanced thermal performance in industry-standard package size Applications * Synchronous rectifier * DC/DC converter 5 6 7 8 Bottom-side Drain Contact 4 3 2 1 Absolute Maximum Ratings Symbol VDSS VGSS ID PD TJ, TSTG Drain-Source Voltage Gate-Source Voltage Drain Current - Continuous - Pulsed Maximum Power Dissipation TA=25oC unless otherwise noted Parameter Ratings 40 20 (Note 1a) Units V V A W C 15.3 60 3.0 -55 to +150 (Note 1a) Operating and Storage Junction Temperature Range Thermal Characteristics RJA RJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 40 0.5 C/W Package Marking and Ordering Information Device Marking FDS4070N3 Device FDS4070N3 Reel Size 13'' Tape width 12mm Quantity 2500 units 2002 Fairchild Semiconductor Corporation FDS4070N3 Rev B1 (W) FDS4070N3 Electrical Characteristics Symbol EAS IAS BVDSS BVDSS TJ IDSS IGSSF IGSSR VGS(th) VGS(th) TJ RDS(on) ID(on) gFS Ciss Coss Crss td(on) tr td(off) tf Qg Qgs Qgd TA = 25C unless otherwise noted Parameter Drain-Source Avalanche Energy Drain-Source Avalanche Current Test Conditions Single Pulse, VDD=40V, ID=15.3A Min Typ Max 310 15.3 Units mJ A Drain-Source Avalanche Ratings (Note 2) Off Characteristics Drain-Source Breakdown Voltage Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current Gate-Body Leakage, Forward Gate-Body Leakage, Reverse (Note 2) ID = 250 A VGS = 0 V, ID = 250 A, Referenced to 25C VDS = 32 V, VGS = 0 V 40 42 1 100 -100 V mV/C A nA nA VGS = 20 V, VDS = 0 V VGS = -20 V, VDS = 0 V ID = 250 A VDS = VGS, ID = 250 A, Referenced to 25 C VGS = 10 V, ID = 15.3 A VGS = 10 V, ID=15.3A, TJ =125C VGS = 10 V, VDS = 5 V VDS = 10 V, VDS = 20 V, f = 1.0 MHz ID = 15.3 A V GS = 0 V, 2 3.9 -8 5.5 8 30 52 On Characteristics Gate Threshold Voltage Gate Threshold Voltage Temperature Coefficient Static Drain-Source On-Resistance On-State Drain Current Forward Transconductance 5 V mV/C 7.5 12 m A S Dynamic Characteristics Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDD = 20 V, VGS = 10 V, ID = 1 A, RGEN = 6 16 12 41 29 VDS = 20 V, VGS = 10 V ID = 15.3 A, 47 15 14 29 22 66 46 67 ns ns ns ns nC nC nC 2819 600 291 pF pF pF Switching Characteristics Turn-On Delay Time Turn-On Rise Time Turn-Off Delay Time Turn-Off Fall Time Total Gate Charge Gate-Source Charge Gate-Drain Charge FDS4070N3 Rev B1 (W) FDS4070N3 Electrical Characteristics Symbol IS VSD trr Qrr TA = 25C unless otherwise noted Parameter Test Conditions Min Typ Max 2.5 Units A V nS nC Drain-Source Diode Characteristics and Maximum Ratings Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward IS = 2.5 A VGS = 0 V, Voltage Diode Reverse Recovery Time IF = 15.3 A, diF/dt = 100 A/s Diode Reverse Recovery Charge (Note 2) 0.7 32 39 1.2 Notes: 1.
