| FDS4672A May 2001 FDS4672A 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 * 11 A, 40 V. RDS(ON) = 13 m @ VGS = 4.5 V * High performance trench technology for extremely low RDS(ON) * Low gate charge (35 nC typical) * High power and current handling capability Applications * DC/DC converter D D D D 5 6 4 3 2 1 SO-8 S S S G 7 8 Absolute Maximum Ratings Symbol VDSS VGSS ID PD Drain-Source Voltage Gate-Source Voltage Drain Current - Continuous - Pulsed TA=25oC unless otherwise noted Parameter Ratings 40 12 (Note 1a) Units V V A W 11 50 2.5 1.4 1.2 Power Dissipation for Single Operation (Note 1a) (Note 1b) (Note 1c) TJ, TSTG Operating and Storage Junction Temperature Range -55 to +175 50 25 C Thermal Characteristics RJA RJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) C/W C/W Package Marking and Ordering Information Device Marking FDS4672A Device FDS4672A Reel Size 13'' Tape width 12mm Quantity 2500 units 2001 Fairchild Semiconductor Corporation FDS4672A Rev C(W) FDS4672A Electrical Characteristics Symbol BVDSS BVDSS TJ IDSS IGSSF IGSSR TA = 25C unless otherwise noted Parameter Drain-Source Breakdown Voltage Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current Gate-Body Leakage, Forward Gate-Body Leakage, Reverse (Note 2) Test Conditions VGS = 0 V, ID = 250 A ID = 250 A, Referenced to 25C VDS = 32 V, VGS = 0 V VGS = 12 V, VDS = 0 V VGS = -12 V VDS = 0 V VDS = VGS, ID = 250 A ID = 250 A, Referenced to 25C VGS = 4.5 V, ID = 11 A VGS=4.5 V, ID =11A, TJ=125C VGS = 4.5 V, VDS = 5 V VDS = 5 V, ID = 11 A Min 40 Typ Max Units V Off Characteristics 37 1 100 -100 mV/C A nA nA 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 0.8 1.2 -4 10 15 2.0 V mV/C 13 21 m A 50 65 S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = 20 V, V GS = 0 V, f = 1.0 MHz 4766 346 155 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 = 4.5 V, RGEN = 6 17 9 43 14 31 18 68 25 49 ns ns ns ns nC nC nC VDS = 20 V, ID = 11 A, VGS = 4.5 V 35 7.8 8.8 Drain-Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward VGS = 0 V, IS = 2.1 A Voltage 2.1 (Note 2) A V 0.7 1.2 Notes: 1.
