| FDS3680 November 2000 FDS3680 100V 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. 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. Features * 5.2 A, 100 V. RDS(ON) = 46 m @ VGS = 10 V RDS(ON) = 51 m @ VGS = 6 V * Low gate charge * Fast switching speed * High performance trench technology for extremely low RDS(ON) * High power and current handling capability D D D D 5 6 7 4 3 2 1 SO-8 S S S G 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 100 20 (Note 1a) Units V V A W 5.2 50 2.5 1.2 1.0 -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 RJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 50 25 C/W C/W Package Marking and Ordering Information Device Marking FDS3680 Device FDS3680 Reel Size 13'' Tape width 12mm Quantity 2500 units FDS3680 Rev C (W) 2000 Fairchild Semiconductor Corporation FDS3680 Electrical Characteristics Symbol WDSS IAR TA = 25C unless otherwise noted Parameter Single Pulse Drain-Source Avalanche Energy Maximum Drain-Source Avalanche Current 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 VDD = 50 V, ID = 5.2 A Min Typ Max Units 245 5.2 mJ A Drain-Source Avalanche Ratings (Note 2) Off Characteristics BVDSS BVDSS ===TJ IDSS IGSSF IGSSR VGS = 0 V, ID = 250 A ID = 250 A, Referenced to 25C VDS = 80 V, VGS = 20 V, VGS = -20 V, VGS = 0 V VDS = 0 V VDS = 0 V 100 101 10 100 -100 V mV/C A nA nA On Characteristics VGS(th) VGS(th) ===TJ RDS(on) Gate Threshold Voltage Gate Threshold Voltage Temperature Coefficient Static Drain-Source On-Resistance On-State Drain Current Forward Transconductance VDS = VGS, ID = 250 A ID = 250 A, Referenced to 25C VGS = 10 V, ID = 5.2 A VGS = 10 V, ID = 5.2 A, TJ=125C VGS = 6 V, ID = 4.5 A VGS = 10 V, VDS = 5 V VDS = 5 V, ID = 5.2 A 2 2.4 -6.5 32 61 34 4 V mV/C 46 92 51 m ID(on) gFS 25 25 A S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = 50 V, f = 1.0 MHz V GS = 0 V, 1735 176 53 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 = 50 V, VGS = 10 V, ID = 1 A, RGEN = 10 14 8.5 63 21 25 17 94 34 53 ns ns ns ns nC nC nC VDS = 50 V, VGS = 10 V ID = 6 A, 38 8.1 9.2 Drain-Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward Voltage VGS = 0 V, IS = 2.1 A (Note 2) 2.1 0.73 1.2 A V Notes: 1.
