FDS3890 80V N-Channel Dual PowerTrench MOSFET General Description Features 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. 4.7 A, 80 V. RDS(ON) = 44 m @ VGS = 10 V RDS(ON) = 50 m @ VGS = 6 V * Fast switching speed These MOSFETs feature faster switching and lower gate charge than other MOSFETs with comparable RDS(ON) specifications. The result is a MOSFET that is easy and safer to drive (even at very high frequencies), and DC/DC power supply designs with higher overall efficiency. * High performance trench technology for extremely low RDS(ON) * High power and current handling capability D1 D1 5 D2 6 D2 4 3 Q1 7 SO-8 S2 G2 S1 G1 Absolute Maximum Ratings Symbol 8 2 Q2 1 TA=25oC unless otherwise noted Ratings Units VDSS Drain-Source Voltage Parameter 80 V VGSS Gate-Source Voltage 20 V ID Drain Current 4.7 A PD Power Dissipation for Dual Operation - Continuous (Note 1a) - Pulsed 20 2 Power Dissipation for Single Operation TJ, TSTG (Note 1a) 1.6 (Note 1b) 1.0 (Note 1c) 0.9 W -55 to +175 C (Note 1a) 78 C/W (Note 1) 40 C/W Operating and Storage Junction Temperature Range Thermal Characteristics RJA Thermal Resistance, Junction-to-Ambient RJC Thermal Resistance, Junction-to-Case Package Marking and Ordering Information Device Marking Device Reel Size Tape width Quantity FDS3890 FDS3890 13'' 12mm 2500 units 2001 Fairchild Semiconductor Corporation FDS3890 Rev B(W) FDS3890 February 2001 Symbol TA = 25C unless otherwise noted Parameter Test Conditions Min Typ Max Units Drain-Source Avalanche Ratings (Note 2) W DSS IAR Single Pulse Drain-Source Avalanche Energy Maximum Drain-Source Avalanche Current VDD = 40 V, ID = 4.7 A 175 mJ 4.7 A Off Characteristics BVDSS Drain-Source Breakdown Voltage VGS = 0 V, ID = 250 A BVDSS TJ IDSS Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current ID = 250 A, Referenced to 25C VDS = 64 V, VGS = 0 V 1 A IGSSF Gate-Body Leakage, Forward VGS = 20 V, VDS = 0 V 100 nA IGSSR Gate-Body Leakage, Reverse VGS = -20 V VDS = 0 V -100 nA 4 V On Characteristics 80 V 86 mV/C (Note 2) VGS(th) Gate Threshold Voltage VDS = VGS, ID = 250 A VGS(th) TJ RDS(on) Gate Threshold Voltage Temperature Coefficient Static Drain-Source On-Resistance ID = 250 A, Referenced to 25C -6 VGS = 10 V, ID = 4.7 A ID = 4.4 A VGS = 6.0 V, VGS = 10 V, ID = 4.7 A, TJ = 125C 34 37 60 ID(on) On-State Drain Current VGS = 10 V, VDS = 5 V gFS Forward Transconductance VDS = 10 V, ID = 4.7 A 24 S VDS = 40 V, f = 1.0 MHz V GS = 0 V, 1180 pF 2 2.3 mV/C 44 50 82 20 m A 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) 171 pF 50 pF (Note 2) 11 20 ns 8 16 ns Turn-Off Delay Time 26 50 ns tf Turn-Off Fall Time 12 25 ns Qg Total Gate Charge 25 35 nC Qgs Gate-Source Charge Qgd Gate-Drain Charge VDD =40 V, VGS = 10 V, VDS = 40 V, VGS = 10 V ID = 1 A, RGEN = 6 ID = 4.7 A, 4.5 nC 5.8 nC Drain-Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward VGS = 0 V, IS = 1.3 A Voltage (Note 2) 0.74 1.3 A 1.2 V Notes: 1.
