Note 1. Ratings apply for zero or negative gate voltage. Devices should not be tested for blocking capability in a manner such that the voltage applied exceeds the rated blocking voltage. Note 2. Devices should not be operated with a positive bias applied to the gate concurrently with a negative potential applied to the anode.Electrical Characteristics: (T = +25C unles otherwise specified) C Parameter Symbol Test Conditions Min Typ Max Unit Peak Forward or Reverse Blocking Current I , Rated V or V , T = +25C 10 A J DRM DRM RRM I Gate Open RRM T = +100C 2 mA J Gate Trigger Current, Continuous DC I V = 7V, R = 100, 10 30 mA GT D L Note 3 T = 40C 60 mA C Gate Trigger Voltage, Continuous DC V 0.75 1.5 V V = 7V, R = 100 GT D L T = 40C 2.5 V C T = +100C 0.2 V J Forward ON Voltage v I = 15.7A, Note 4 1.4 2.0 V TM TM Holding Current I 10 30 mA V = 7V, Gate Open H D T = 40C 60 mA C TurnOn Time (t + t ) t I = 20mA, I = 5A, V = Rated V 1 s d r on G F D DRM Turn Off Time t 15 s I = 5A, I = 5A, off F R V = Rated V , D DRM T = +100C 25 s J dv/dt = 30V/s Forward Voltage Application Rate dv/dt Gate Open, T = +100C, 50 V/s J (Exponential) V = Rated V D DRM Note 3.
