| FDS6679 March 2005 FDS6679 30 Volt P-Channel PowerTrench(R) MOSFET General Description This P-Channel MOSFET has been designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers, and battery chargers. 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 * -13 A, -30 V. RDS(ON) = 9 m @ VGS = -10 V RDS(ON) = 13 m @ VGS = - 4.5 V * Extended VGSS range (25V) for battery applications * High performance trench technology for extremely low RDS(ON) * High power and current handling capability D D D D 5 6 4 3 2 1 SO-8 S S S G 7 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 -30 25 (Note 1a) Units V V A W -13 -50 2.5 1.2 1.0 -55 to +175 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 FDS6679 Device FDS6679 Reel Size 13'' Tape width 12mm Quantity 2500 units (c)2005 Fairchild Semiconductor Corporation FDS6679 Rev C1 (W) FDS6679 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-Body Leakage (Note 2) Test Conditions VGS = 0 V, ID = -250 A ID = -250 A, Referenced to 25C VDS = -24 V, VGS = 25 V, VGS = 0 V VDS = 0 V Min -30 Typ Max Units V Off Characteristics -23 -1 100 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 VDS = VGS, ID = -250 A ID = -250 A, Referenced to 25C VGS = -10 V, ID = -13 A ID = -11 A VGS = -4.5 V, VGS=-10 V, ID =-13 A, TJ=125C VGS = -10 V, VDS = -5 V VDS = -5 V, ID = -13 A -1 -1.6 5 7.3 10 9.5 -3 V mV/C 9 13 13 m ID(on) gFS -50 44 A S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = -15 V, f = 1.0 MHz V GS = 0 V, 3939 972 498 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 = -15 V, VGS = -10 V, ID = -1 A, RGEN = 6 19 10 110 65 34 20 176 104 100 ns ns ns ns nC nC nC VDS = -15 V, VGS = -10 V ID = -13 A, 71 12 15 Drain-Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward VGS = 0 V, IS = -2.1 A Voltage -2.1 (Note 2) A V -0.7 -1.2 Notes: 1. RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins.
