Rev. A, May 2004 SSM1N45B ©2004 Fairchild Semiconductor Corporation Electrical Characteristics TC = 25°C unless otherwise noted Notes: 1. Repetitive Rating : Pulse width limited by maximum junction temperature 2. L = 75mH, IAS = 1.6A, VDD = 50V, RG = 25 Ω, Starting TJ = 25°C 3. ISD ≤ 0.5A, di/dt ≤ 300A/µs, VDD ≤ BVDSS, Starting TJ = 25°C 4. Pulse Test : Pulse width ≤ 300µs, Duty cycle ≤ 2% 5. Essentially independent of operating temperature 6. a) Reference point of the RθJL is the drain lead b) When mounted on the minimum pad size recommended (PCB Mount) (RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance. RθCA is determined by the users board design) Symbol Parameter Test Conditions Min Typ Max Units Off Characteristics BVDSS Drain-Source Breakdown Voltage VGS = 0 V, ID = 250 µA 450 -- -- V ∆BVDSS / ∆TJ Breakdown Voltage Temperature Coefficient ID = 250 µA, Referenced to 25°C -- 0.5 -- V/°C IDSS Zero Gate Voltage Drain Current VDS = 450 V, VGS = 0 V -- -- 10 µA VDS = 360 V, TC = 125°C -- -- 100 µA IGSSF Gate-Body Leakage Current, Forward VGS = 50 V, VDS = 0 V -- -- 100 nA IGSSR Gate-Body Leakage Current, Reverse VGS = -50 V, VDS = 0 V -- -- -100 nA On Characteristics VGS(th) Gate Threshold Voltage VDS = VGS, ID = 250 µA 2.3 3.0 3.7 V VDS = VGS, ID = 250 mA 3.5 4.2 4.9 V RDS(on) Static Drain-Source On-Resistance VGS = 10 V, ID = 0.25 A -- 3.4 4.25 Ω gFS Forward Transconductance VDS = 50 V, ID = 0.25 A (Note 4) -- 0.7 -- S Dynamic Characteristics Ciss Input Capacitance VDS = 25 V, VGS = 0 V, f = 1.0 MHz -- 185 240 pF Coss Output Capacitance -- 29 40 pF Crss Reverse Transfer Capacitance -- 6.5 8.5 pF Switching Characteristics td(on) Turn-On Delay Time VDD = 225 V, ID = 0.5 A, RG = 25 Ω (Note 4,5) -- 7.5 25 ns tr Turn-On Rise Time -- 21 50 ns td(off) Turn-Off Delay Time -- 23 55 ns tf Turn-Off Fall Time -- 36 80 ns Qg Total Gate Charge VDS = 360 V, ID = 0.5 A, VGS = 10 V (Note 4,5) -- 6.5 8.5 nC Qgs Gate-Source Charge -- 0.9 -- nC Qgd Gate-Drain Charge -- 3.2 -- nC Drain-Source Diode Characteristics and Maximum Ratings IS Maximum Continuous Drain-Source Diode Forward Current -- -- 0.5 A ISM Maximum Pulsed Drain-Source Diode Forward Current -- -- 4.0 A VSD Drain-Source Diode Forward Voltage VGS = 0 V, IS = 0.5 A -- -- 1.4 V trr Reverse Recovery Time VGS = 0 V, IS = 0.5 A, dIF / dt = 100 A/µs (Note 4) -- 102 -- ns Qrr Reverse Recovery Charge -- 0.26 -- µC
