Chopper Regulator, DC/DC Converter and Motor Drive Applications
1. Low drain-source ON-resistance : RDS (ON) = 8.0 Ω (typ.)
2. High forward transfer admittance : |Yfs| = 0.9 S (typ.)
3. Low leakage current : IDSS = 100 μA (max) (VDS = 720 V)
4. Enhancement mode : Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA)
Absolute Maximum Ratings (Ta = 25°C)
1. Drain-source voltage : VDSS = 900 V
2. Drain-gate voltage (RGS = 20 kΩ) : VDGR = 900 V
3. Drain power dissipation (Tc = 25°C) : PD = 40 W
