FDS3890 February 2001 FDS3890 80V N-Channel Dual 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 4.7 A, 80 V. RDS(ON) = 44 mΩ @ VGS = 10 V RDS(ON) = 50 mΩ @ VGS = 6 V • Fast switching speed • High performance trench technology for extremely low RDS(ON) • High power and current handling capability D1 D1 D2 D2 S1 G1 5 6 7 Q1 4 3 2 Q2 SO-8 S2 8 1 G2 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 80 ± 20 (Note 1a) Units V V A W 4.7 20 2 Power Dissipation for Dual Operation Power Dissipation for Single Operation (Note 1a) (Note 1b) (Note 1c) 1.6 1.0 0.9 –55 to +175 °C TJ, TSTG Operating and Storage Junction Temperature Range Thermal Characteristics RθJA RθJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 78 40 °C/W °C/W Package Marking and Ordering Information Device Marking FDS3890 Device FDS3890 Reel Size 13’’ Tape width 12mm Quantity 2500 units 2001 Fairchild Semiconductor Corporation FDS3890 Rev B(W) FDS3890 Electrical Characteristics Symbol W DSS IAR TA = 25°C 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 = 40 V, ID = 4.7 A Min Typ Max Units 175 4.7 mJ A Drain-Source Avalanche Ratings (Note 2) Off Characteristics BVDSS ∆BVDSS ∆TJ IDSS IGSSF IGSSR VGS = 0 V, ID = 250 µA ID = 250 µA, Referenced to 25°C VDS = 64 V, VGS = 20 V, VGS = –20 V VGS = 0 V VDS = 0 V VDS = 0 V 80 86 1 100 –100 V mV/°C µA 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 µA ID = 250 µA, Referenced to 25°C VGS = 10 V, ID = 4.7 A ID = 4.4 A VGS = 6.0 V, VGS = 10 V, ID = 4.7 A, TJ = 125°C VGS = 10 V, VDS = 10 V, VDS = 5 V ID = 4.7 A 2 2.3 –6 34 37 60 4 V mV/°C 44 50 82 mΩ ID(on) gFS 20 24 A S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = 40 V, f = 1.0 MHz V GS = 0 V, 1180 171 50 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 =40 V, VGS = 10 V, ID = 1 A, RGEN = 6 Ω 11 8 26 12 20 16 50 25 35 ns ns ns ns nC nC nC VDS = 40 V, VGS = 10 V ID = 4.7 A, 25 4.5 5.8 Drain–Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain–Source Diode Forward Current Drain–Source Diode Forward VGS = 0 V, IS = 1.3 A Voltage 1.3 (Note 2) A V 0.74 1.2 Notes: 1.
