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: (TC = +25°C unles otherwise specified) Parameter Symbol Test Conditions Min Typ Peak Forward or Reverse Blocking Current IDRM, IRRM Rated VDRM or VRRM, TJ = +25°C Gate Open TJ = +100°C − − 10 μA − − 2 mA VD = 7V, RL = 100Ω, Note 3 − 10 30 mA − − 60 mA − 0.75 1.5 V TC = −40°C − − 2.5 V TJ = +100°C 0.2 − − V Gate Trigger Current, Continuous DC Gate Trigger Voltage, Continuous DC Forward “ON” Voltage Holding Current IGT VGT TC = −40°C VD = 7V, RL = 100Ω Max Unit vTM ITM = 15.7A, Note 4 − 1.4 2.0 V IH VD = 7V, Gate Open − 10 30 mA − − 60 mA TC = −40°C Turn−On Time (td + tr) ton IG = 20mA, IF = 5A, VD = Rated VDRM − 1 − μs Turn−Off Time toff IF = 5A, IR = 5A, VD = Rated VDRM, dv/dt = 30V/μs − 15 − μs − 25 − μs − 50 − V/μs Forward Voltage Application Rate (Exponential) dv/dt TJ = +100°C Gate Open, TJ = +100°C, VD = Rated VDRM Note 3.
