FDS6680S 30V N-Channel PowerTrench SyncFET™ General Description Features The FDS6680S is designed to replace a single SO-8 MOSFET and Schottky diode in synchronous DC:DC power supplies. This 30V MOSFET is designed to maximize power conversion efficiency, providing a low RDS(ON) and low gate charge. The FDS6680S includes an integrated Schottky diode using Fairchild’s monolithic SyncFET technology. The performance of the FDS6680S as the low-side switch in a synchronous rectifier is indistinguishable from the performance of the FDS6680 in parallel with a Schottky diode. • 11.5 A, 30 V. • Includes SyncFET Schottky body diode • Low gate charge (17nC typical) • High performance trench technology for extremely low RDS(ON) and fast switching • High power and current handling capability Applications RDS(ON) = 0.011 Ω @ VGS = 10 V RDS(ON) = 0.016 Ω @ VGS = 4.5 V • DC/DC converter • Motor drives D D D D SO-8 S S S G Absolute Maximum Ratings Symbol 5 4 6 3 7 2 8 1 o TA=25 C unless otherwise noted Parameter Ratings Units VDSS Drain-Source Voltage 30 V VGSS Gate-Source Voltage ±20 V ID Drain Current 11.5 A – Continuous (Note 1a) – Pulsed PD 50 Power Dissipation for Single Operation (Note 1a) 2.5 (Note 1b) 1.2 (Note 1c) TJ, TSTG W 1 -55 to +150 °C (Note 1a) 50 °C/W (Note 1) 25 °C/W Operating and Storage Junction Temperature Range Thermal Characteristics RθJA Thermal Resistance, Junction-to-Ambient RθJC Thermal Resistance, Junction-to-Case Package Marking and Ordering Information Device Marking Device Reel Size Tape width Quantity FDS6680S FDS6680S 13’’ 12mm 2500 units 2000 Fairchild Semiconductor Corporation FDS6680S Rev B (W) FDS6680S February 2000 PRELIMINARY Symbol Parameter TA = 25°C unless otherwise noted Test Conditions Min Typ Max Units Off Characteristics BVDSS Drain–Source Breakdown Voltage ∆BVDSS ∆TJ IDSS Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current IGSSF Gate–Body Leakage, Forward VGS = 20 V, IGSSR Gate–Body Leakage, Reverse VGS = –20 V On Characteristics VGS = 0 V, ID = 1 mA 30 19 ID = 1 mA, Referenced to 25°C VDS = 24 V, V VGS = 0 V mV/°C 1 mA VDS = 0 V 100 nA VDS = 0 V –100 nA 3 V (Note 2) VGS(th) Gate Threshold Voltage VDS = VGS, ID = 1 mA ∆VGS(th) ∆TJ RDS(on) Gate Threshold Voltage Temperature Coefficient Static Drain–Source On–Resistance ID = 1 mA, Referenced to 25°C 1 2 -3.3 VGS = 10 V, ID = 11.5 A VGS = 4.5 V, ID = 9.5 A VGS=10 V, ID =11.5A, TJ=125°C 9.5 13.5 17 ID(on) On–State Drain Current VGS = 10 V, VDS = 5 V gFS Forward Transconductance VDS = 15 V, ID = 11.5 A VDS = 15 V, f = 1.0 MHz V GS = 0 V, mV/°C 11 16 23 50 mΩ A 27 S 2010 pF 526 pF 186 pF Dynamic Characteristics Ciss Input Capacitance Coss Output Capacitance Crss Reverse Transfer Capacitance Switching Characteristics td(on) Turn–On Delay Time tr Turn–On Rise Time td(off) (Note 2) 10 18 10 18 ns Turn–Off Delay Time 34 55 ns tf Turn–Off Fall Time 14 23 ns Qg Total Gate Charge 17 24 nC Qgs Gate–Source Charge Qgd Gate–Drain Charge VDS = 15 V, VGS = 10 V, VDS = 15 V, VGS = 5 V ID = 1 A, RGEN = 6 Ω ID = 11.5 A, ns 6.2 nC 5.5 nC Drain–Source Diode Characteristics and Maximum Ratings IS Maximum Continuous Drain–Source Diode Forward Current VSD trr Drain–Source Diode Forward Voltage Diode Reverse Recovery Time Qrr Diode Reverse Recovery Charge VGS = 0 V, IS = 3.5 A VGS = 0 V, IS = 7 A IF = 11.5A, diF/dt = 300 A/µs (Note 2) 0.45 0.6 20 (Note 3) 19.7 (Note 2) 3.5 A 0.7 V nS nC Notes: 1.
