MC3948DV规格书

FreescaleThese miniature surface mount MOSFETs utilize High Cell Density process. Low rDS(on)assures minimal power loss and conserves energy, making this device ideal for use in power management circuitry. Typical applications are DC-DC converters, power management in portable and battery-powered products such as computers, printers, PCMCIA cards, cellular and cordless telephones.•LowrDS(on)Provides Higher Efficiency and Extends Battery Life•Miniature TSOP-6 Surface Mount Package Saves Board Space•Very fast switching•Lower gate charge (2.2 nC)Si 39 4 8 DV/ MC39 4 8 DV Dual N-Channel Logical Level MOSFETPRODUCT SUMMARYVDS (V)rDS(on) (OHM)0.099 @ VGS = 10 V300.142 @ VGS = 4.5VID (A)2.52.0123654 ABSOLUTE MAXIMUM RATINGS (TA = 25 C UNLESS OTHERWISE NOTED)ParameterSymbolMaximumUnits30Drain-Source VoltageVDSVVGSGate-Source Voltage±20Continuous Drain CurrentPulsed Drain CurrentbaaoTA=25CTA=70CooIDIDMIS2.5210±0.80.950.7AWoAContinuous Source Current (Diode Conduction)Power DissipationaTA=25CTA=70CooPDOperating Junction and Storage Temperature RangeTJ, Tstg-55 to 150CTHERMAL RESISTANCE RATINGSParameterMaximum Junction-to-Ambientat <= 5 secSteady-StateSymbolMaximumUnitsRΤΗJA130176oC/WNotesa.Surface Mounted on 1” x 1” FR4 Board.b.Pulse width limited by maximum junction temperature1www.freescale.net.cn FreescaleSi 39 4 8 DV/ MC39 4 8 DV SPECIFICATIONS (TA = 25C UNLESS OTHERWISE NOTED)ParameterStaticDrain-Source Breakdown VoltageGate-Threshold VoltageGate-Body LeakageZero Gate Voltage Drain CurrentOn-State Drain CurrentAAoSymbolV(BR)DSSVGS(th)IGSSIDSSID(on)rDS(on)gfsVSDQgQgsQgdtd(on)trtd(off)tfTest ConditionsVGS = 0 V, ID = -250 uAVDS = VGS, ID = -250 uAVDS = 0 V, VGS = 20 VLimitsUnitMinTypMax301.00VnAuAA0.0820.1133-0.72.30.70.96.5111330.0990.142-1.23.31.01.41319247ΩSV1.853.1±100VDS = 240 V, VGS = 0 VVDS = 24 V, VGS = 0 V, TJ = 55Co11010Drain-Source On-ResistanceForward TranconductanceDiode Forward VoltageAVDS = 5 V, VGS = 10 VVGS = 10 V, ID = -2.5 AVGS = 4.5 V, ID = 2.0 AVDS = 5 V, ID = 2.5 AIS = -1.6 A, VGS = 0 VDynamicbTotal Gate ChargeGate-Source ChargeGate-Drain ChargeVDS = 15 V, VGS = 5 V, ID = 2.5 AnCSwitchingTurn-On Delay TimeRise TimeTurn-Off Delay TimeFall-TimeVDD = 5 V, ID = 2.5 A, VGEN = 10 V, RG = 6 ΩnsNotesa.Pulse test: PW <= 300us duty cycle <= 2%.b.Guaranteed by design, not subject to production testing.FREESCALE reserves the right to make changes without further notice to any products herein. freescale makes no warranty, representation or guarantee regarding the suitability of its products for any particular purpose, nor does freescale assume any liability arising ou tof the application or use of any product or circuit, and specifically disclaims any and all liability, including without limitation special, consequential or incidental damages. “Typical” parameters which may be provided in freescale datasheets and/or specifications can and do vary in different applications and actual performance may vary over time.
