| May 1994 NDP608A / NDP608AE / NDP608B / NDP608BE NDB608A / NDB608AE / NDB608B / NDB608BE N-Channel Enhancement Mode Field Effect Transistor General Description These N-channel enhancement mode power field effect transistors are produced using Fairchild's proprietary, high cell density, DMOS technology. This very high density process has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulses in the avalanche and commutation modes. These devices are particularly suited for low voltage applications such as automotive, DC/DC converters, PWM motor controls, and other battery powered circuits where fast switching, low in-line power loss, and resistance to transients are needed. Features 36 and 32A, 80V. RDS(ON) = 0.042and 0.045. Critical DC electrical parameters specified at elevated temperature. Rugged internal source-drain diode can eliminate the need for an external Zener diode transient suppressor. 175C maximum junction temperature rating. High density cell design (3 million/in) for extremely low RDS(ON). TO-220 and TO-263 (D2PAK) package for both through hole and surface mount applications. _____________________________________________________________________ D G S Absolute Maximum Ratings Symbol Parameter VDSS VDGR VGSS ID PD Drain-Source Voltage Drain-Gate Voltage (RGS < 1 M) Gate-Source Voltage - Continuous - Nonrepetitive (tP < 50 s) Drain Current - Continuous - Pulsed Total Power Dissipation @ TC = 25C Derate above 25C TJ,TSTG TL TC = 25C unless otherwise noted NDP608A NDP608AE NDB608A NDB608AE 80 80 20 40 36 144 100 0.67 NDP608B NDP608BE NDB608B NDB608BE Units V V V V 32 128 A A W W/C C C Operating and Storage Temperature Range Maximum lead temperature for soldering purposes, 1/8" from case for 5 seconds -65 to 175 275 (c) 1997 Fairchild Semiconductor Corporation NDP608.SAM Electrical Characteristics (T Symbol EAS IAR Parameter Single Pulse Drain-Source Avalanche Energy C = 25C unless otherwise noted) Conditions VDD = 25 V, ID = 36 A Type NDP608AE NDP608BE NDB608AE NDB608BE Min Typ Max 200 36 Units mJ A DRAIN-SOURCE AVALANCHE RATINGS (Note 1) Maximum Drain-Source Avalanche Current OFF CHARACTERISTICS BVDSS IDSS IGSSF IGSSR VGS(th) RDS(ON) Drain-Source Breakdown Voltage Zero Gate Voltage Drain Current Gate - Body Leakage, Forward Gate - Body Leakage, Reverse Gate Threshold Voltage Static Drain-Source On-Resistance VGS = 0 V, ID = 250 A VDS = 80 V, VGS = 0 V VGS = 20 V, VDS = 0 V VGS = -20 V, VDS = 0 V VDS = VGS, ID = 250 A VGS = 10 V, ID = 18 A ALL ALL TJ = 125C ALL ALL ALL TJ = 125C NDP608A NDP608AE NDB608A TJ = 125C NDB608AE NDP608B NDP608BE NDB608B TJ = 125C NDB608BE NDP608A NDP608AE NDB608A NDB608AE NDP608B NDP608BE NDB608B NDB608BE gFS Forward Transconductance Input Capacitance Output Capacitance Reverse Transfer Capacitance VDS = 10 V, ID = 18 A VDS = 25 V, VGS = 0 V, f = 1.0 MHz ALL ALL ALL ALL DYNAMIC CHARACTERISTICS 36 2 1.4 2.9 2.3 0.031 0.05 80 250 1 100 -100 4 3.2 0.042 0.08 0.045 0.09 V A mA nA nA V V A ON CHARACTERISTICS (Note 2) VGS = 10 V, ID = 16 A ID(on) On-State Drain Current VGS = 10 V, VDS = 10 V 32 A 10 17.5 1370 390 140 1800 500 200 S pF pF pF Ciss Coss Crss NDP608.SAM Electrical Characteristics (T Symbol tD(ON) tr tD(OFF) tf Qg Qgs Qgd IS Parameter 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 C = 25C unless otherwise noted) Conditions VDD = 40 V, ID = 36 A, VGS = 10 V, RGEN = 7.5 Type ALL ALL ALL ALL Min Typ 11 113 37 69 46 8 25 Max 20 190 60 110 65 Units nS nS nS nS nC nC nC SWITCHING CHARACTERISTICS (Note 2) VDS = 64 V, ID = 36 A, VGS = 10V ALL ALL ALL NDP608A NDP608AE NDB608A NDB608AE NDP608B NDP608BE NDB608B NDB608BE DRAIN-SOURCE DIODE CHARACTERISTICS Maximum Continuos Drain-Source Diode Forward Current 36 A 32 A ISM Maximum Pulsed Drain-Source Diode Forward Current NDP608A NDP608AE NDB608A NDB608AE NDP608B NDP608BE NDB608B NDB608BE 144 A 128 A VSD (Note 2) Drain-Source Diode Forward Voltage Reverse Recovery Time Reverse Recovery Current VGS = 0 V, IS = 18 A VGS = 0 V, IS = 36 A, dIS/dt = 100 A/s ALL TJ = 125C ALL ALL 0.91 0.81 88 6 1.3 1.2 125 9 V V ns A trr Irr RJC RJA THERMAL CHARACTERISTICS Thermal Resistance, Junction-to-Case Thermal Resistance, Junction-to-Ambient ALL ALL 1.5 62.5 C/W C/W Notes: 1.
