March 2003 FDS4770 FDS4770 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 gate charge, low RDS(ON) and fast switching speed. Features * 13.2 A, 40 V. RDS(ON) = 10.5 m @ VGS = 10 V * Low gate charge (30 nC) * High performance trench technology for extremely low RDS(ON) * High power and current handling capability Applications * DC/DC converter D D D D SO-8 DD D D 5 6 7 4 3 2 1 Pin 1 SO-8 G SG S S SS S TA=25oC unless otherwise noted 8 Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current - Continuous - Pulsed Parameter Ratings 40 20 (Note 1a) Units V V A W 13.2 45 2.5 1.4 1.2 -55 to +150 Power Dissipation for Single Operation (Note 1a) (Note 1b) (Note 1c) TJ, TSTG Operating and Storage Junction Temperature Range C Thermal Characteristics RJA RJA RJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1c) (Note 1) 50 125 25 C/W C/W C/W Package Marking and Ordering Information Device Marking FDS4770 Device FDS4770 Reel Size 13'' Tape width 11mm Quantity 2500 units 2003 Fairchild Semiconductor Corporation FDS4770 Rev B (W) FDS4770 Electrical Characteristics Symbol EAS IAS TA = 25C unless otherwise noted Parameter Drain-Source Avalanche Energy Drain-Source Avalanche Current Test Conditions Single Pulse, VDD=20V, ID=13.2A Min Typ Max Units 370 13.2 mJ A Drain-Source Avalanche Ratings (Note 2) Off Characteristics BVDSS BVDSS TJ IDSS IGSSF IGSSR 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 = 20 V, VGS = 0 V VDS = 0 V 40 42 1 100 -100 V mV/C A nA nA VGS = -20 V, VDS = 0 V ID = 250 A VDS = VGS, ID = 250 A, Referenced to 25C VGS = 10 V, ID = 13.2 A VGS = 10 V,ID = 13.2 A, TJ=115C VGS = 10 V, VDS = 10 V, VDS = 5 V ID = 13.2 A 30 45 On Characteristics VGS(th) VGS(th) TJ RDS(on) ID(on) gFS Gate Threshold Voltage Gate Threshold Voltage Temperature Coefficient Static Drain-Source On-Resistance On-State Drain Current Forward Transconductance 2 3.9 -8 6 9 5 V mV/C 7.5 10 m A S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = 20 V, f = 1.0 MHz V GS = 0 V, 2819 600 291 pF pF pF Switching Characteristics td(on) tr td(off) tf Qg Qgs Qgd 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 VDD = 20 V, ID = 1 A, VGS = 10 V, RGEN = 6 16 12 41 29 29 22 66 46 67 ns ns ns ns nC nC nC VDS = 20 V, VGS = 10 V ID = 13.2 A, 47 15 14 FDS4770 Rev B (W) FDS4770 Electrical Characteristics Symbol IS VSD trr Qrr TA = 25C unless otherwise noted Parameter Test Conditions Min Typ Max Units 2.1 A V nS nC Drain-Source Diode Characteristics and Maximum Ratings Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward VGS = 0 V, IS = 2.1 A (Note 2) Voltage Diode Reverse Recovery Time IF = 13.2 A, diF/dt = 100 A/s Diode Reverse Recovery Charge 0.7 32 39 1.2 Notes: 1.
