IRF7809AV

PD-90010 IRF7809AV • • • • • N-Channel Application-Specific MOSFETs Ideal for CPU Core DC-DC Converters Low Conduction Losses Low Switching Losses Minimizes Parallel MOSFETs for high current applications S S S G 1 8 7 A A D D D D 2 Description This new device employs advanced HEXFET Power MOSFET technology to achieve an unprecedented balance of on-resistance and gate charge. The reduced conduction and switching losses make it ideal for high efficiency DC-DC converters that power the latest generation of microprocessors. The IRF7809AV has been optimized for all parameters that are critical in synchronous buck converters including RDS(on), gate charge and Cdv/dt-induced turn-on immunity. The IRF7809AV offers particulary low RDS(on) and high Cdv/dt immunity for synchronous FET applications. The package is designed for vapor phase, infra-red, convection, or wave soldering techniques. Power dissipation of greater than 2W is possible in a typical PCB mount application. 3 6 4 5 SO-8 T o p V ie w DEVICE CHARACTERISTICS… IRF7809AV RDS(on) QG Qsw Qoss 7.0mΩ 41nC 14nC 30nC Absolute Maximum Ratings Parameter Drain-Source Voltage Gate-Source Voltage Continuous Drain or Source Current (VGS ≥ 4.5V) Pulsed Drain Current Power Dissipation TA = 25°C TL = 90°C Junction & Storage Temperature Range Continuous Source Current (Body Diode) Pulsed Source Current Thermal Resistance Parameter Maximum Junction-to-Ambientƒ Maximum Junction-to-Lead RθJA RθJL Max. 50 20 Units °C/W °C/W TJ, TSTG IS ISM TA = 25°C TL = 90°C IDM PD Symbol VDS VGS ID IRF7809A V 30 ±12 13.3 14.6 100 2.5 3.0 –55 to 150 2.5 50 °C A W A Units V 10/26/00 IRF7809AV Electrical Characteristics Parameter Drain-to-Source Breakdown Voltage Static Drain-Source on Resistance Gate Threshold Voltage Drain-Source Leakage Current BVDSS RDS(on) VGS(th) IDSS 1.0 30 150 IGSS QG QG QGS1 QGS2 QGD Qsw Qoss RG td (on) tr td tf Ciss Coss – – – (off) Min 30 Typ – 7.0 Max – 9.0 Units V mΩ V Conditions VGS = 0V, ID = 250µA VGS = 4.5V, ID = 15A‚ VDS = VGS,ID = 250µA VDS = 24V, VGS = 0 VDS = 24V, VGS = 0, Tj = 100°C VGS = ±12V VGS=5V, ID=15A, VDS=20V VGS = 5V, VDS< 100mV VDS = 20V, ID = 15A Current* µA nA Gate-Source Leakage Current* Total Gate Chg Cont FET Total Gate Chg Sync FET Pre-Vth Gate-Source Charge Post-Vth Gate-Source Charge Gate to Drain Charge Switch Chg(Qgs2 + Qgd) Output Charge* Gate Resistance Turn-on Delay Time Rise Time Turn-off Delay Time Fall Time Input Capacitance Output Capacitance ±100 41 36 7.0 2.3 12 14 30 1.5 14 36 96 10 3780 1060 130 – – – 21 45 62 54 nC ID=15A, VDS=16V VDS = 16V, VGS = 0 Ω VDD = 16V, ID = 15A ns VGS = 5V Clamped Inductive Load pF VDS = 16V, VGS = 0 Reverse Transfer Capacitance Crss Source-Drain Rating & Characteristics Parameter Diode Forward Voltage* Reverse Recovery Charge „ Reverse Recovery Charge (with Parallel Schottky)„ VSD Qrr Qrr(s) 120 Min Typ Max 1.3 Units V nC Conditions IS = 15A‚, VGS = 0V di/dt ~ 700A/µs VDS = 16V, VGS = 0V, IS = 15A 150 nC di/dt = 700A/µs (with 10BQ040) VDS = 16V, VGS = 0V, IS = 15A Notes:  ‚ ƒ „ … Repetitive rating; pulse width limited by max. junction temperature.
