| FDS6912A July 2003 FDS6912A Dual N-Channel Logic Level PowerTrench(R) MOSFET General Description These N-Channel Logic Level MOSFETs are produced using Fairchild Semiconductor's advanced PowerTrench process that has been especially tailored to minimize the on-state resistance and yet maintain superior switching performance. These devices are well suited for low voltage and battery powered applications where low in-line power loss and fast switching are required. Features * 6 A, 30 V. RDS(ON) = 28 m @ VGS = 10 V RDS(ON) = 35 m @ VGS = 4.5 V * Fast switching speed * Low gate charge * High performance trench technology for extremely low RDS(ON) * High power and current handling capability D2 D D2 D DD1 D1 D 5 6 7 Q1 4 3 2 Q2 SO-8 Pin 1 SO-8 G2 S2 S G1 S1 G S 8 1 S 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 30 20 (Note 1a) Units V V A W 6 20 1.6 1.0 0.9 -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) 78 40 C/W C/W Package Marking and Ordering Information Device Marking FDS6912A Device FDS6912A Reel Size 13'' Tape width 12mm Quantity 2500 units (c)2003 Fairchild Semiconductor Corporation FDS6912A Rev D(W) FDS6912A Electrical Characteristics Symbol BVDSS BVDSS TJ IDSS IGSS TA = 25C unless otherwise noted Parameter Drain-Source Breakdown Voltage Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current Gate-Source Leakage (Note 2) Test Conditions VGS = 0 V, ID = 250 A ID = 250 A, Referenced to 25C VDS = 24 V, VGS = 0 V VDS = 24 V, VGS = 0 V, TJ = 55C VGS = 20 V, VDS = 0 V VDS = VGS, ID = 250 A ID = 250 A, Referenced to 25C VGS = 10 V, ID = 6 A VGS = 4.5 V, ID = 5 A VGS = 10 V, ID = 6 A,TJ = 125C VGS = 10 V, VDS = 5 V VDS = 10 V, ID = 6 A Min 30 Typ Max Units V Off Characteristics 25 1 10 100 mV/C A 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 1 1.9 -4.5 19 24 27 3 V mV/C 28 35 44 m ID(on) gFS 20 25 A S Dynamic Characteristics Ciss Coss Crss RG Input Capacitance Output Capacitance Reverse Transfer Capacitance Gate Resistance (Note 2) VDS = 15 V, f = 1.0 MHz V GS = 0 V, 575 145 65 2.1 pF pF pF VGS = 15 mV, f = 1.0 MHz 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 = 15 V, VGS = 10 V, ID = 1 A, RGEN = 6 8 5 23 3 16 10 37 6 8.1 ns ns ns ns nC nC nC VDS = 15 V, VGS = 5 V ID = 6 A, 5.8 1.7 2.1 Drain-Source Diode Characteristics and Maximum Ratings IS VSD trr Qrr Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward Voltage Diode Reverse Recovery Time Diode Reverse Recovery Charge VGS = 0 V, IF = 6 A, IS = 1.3 A (Note 2) 1.3 0.75 20 10 1.2 A V nS nC diF/dt = 100 A/s Notes: 1.
