S i9424DY January 2001 Si9424DY Single P-Channel 2.5V Specified PowerTrench® MOSFET General Description This P-Channel 2.5V specified MOSFET is produced using Fairchild Semiconductor's advanced PowerTrench process that has been especially tailored to minimize 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 • -8.0 A, -20 V. RDS(on) = 0.024 Ω @ VGS = -4.5 V RDS(on) = 0.032 Ω @ VGS = -2.5 V. • • • • Low gate charge (23nC typical). Fast switching speed. High performance trench technology for extremely low RDS(ON). High power and current handling capability. Applications • • • DC/DC converter Load switch Battery Protection 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 = 25°C unless otherwise noted Parameter Ratings -20 (Note 1a) Units V V A W ±10 -8.0 -50 2.5 1.2 1 -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 RθJA RθJC Thermal Resistance, Junction-to-Ambient Thermal Resistance, Junction-to-Case (Note 1a) (Note 1) 50 25 °C/W °C/W Package Outlines and Ordering Information Device Marking 9424 Device Si9424DY Reel Size 13’’ Tape Width 12mm Quantity 2500 units ©2001 Fairchild Semiconductor International Si9424DY Rev.A S i9424DY Electrical Characteristics Symbol Parameter TA = 25°C unless otherwise noted Test Conditions VGS = 0 V, ID = -250 µA ID = -250 µA, Referenced to 25°C VDS = -16 V, VGS = 0 V VGS = 10 V, VDS = 0 V Min Typ Max Units Off Characteristics BVDSS ∆BVDSS ∆TJ IDSS IGSSF IGSSR Drain-Source Breakdown Voltage Breakdown Voltage Temperature Coefficient Zero Gate Voltage Drain Current Gate-Body Leakage Current, Forward -20 -24 -1 100 -100 V mV/°C µA nA nA Gate-Body Leakage Current, Reverse VGS = -10 V, VDS = 0 V (Note 2) 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 = -4.5 V, ID = -8 A VGS = -4.5 V, ID = -8 A ,TJ=125°C VGS = -2.5 V, ID = -7 A VGS = -4.5 V, VDS = -5.0 V VDS = -5 V, ID = -8 A -0.4 -0.8 5 -1.5 V mV/°C Ω 0.019 0.024 0.026 0.039 0.027 0.032 -50 28 ID(on) gFS A S Dynamic Characteristics Ciss Coss Crss Input Capacitance Output Capacitance Reverse Transfer Capacitance (Note 2) VDS = -10 V, VGS = 0 V, f = 1.0 MHz 2260 500 205 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 = -10 V, ID = -1 A, VGS = -4.5 V, RGEN = 6 Ω 8 15 98 35 16 27 135 55 33 ns ns ns ns nC nC nC VDS = -10 V, ID = -8 A, VGS = -5 V, 23 5.5 4 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 -0.75 -1.2 A V Notes: 1: RθJA is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of the drain pins.
