NTE5446 is a discontinued device and is replaced by NTE5448. Note 2. Ratings apply for zero or negative gate voltage but positive gate voltage shall not be applied concurrently with a negative potential on the anode. When checking forward or reverse blocking capability, thyristor devices should not be tested with a constant current source in a manner that the voltage applied exceeds the rated blocking voltage. Electrical Characteristics: (TC = +25°C unless otherwise specified) Parameter Symbol Peak Forward or Reverse Blocking Current IDRM, IRRM Gate Trigger Current (Continuous DC) IGT Gate Trigger Voltage (Continuous DC) VGT Test Conditions VTM Holding Current IHold Typ Max Unit Rated VDRM or VRRM, Gate Open TJ = +25°C − − 10 μA TJ= +100°C − − 2 mA VD = 7V, RL = 100Ω TC = +25°C − 7 30 mA TC = −40°C − − 60 mA TC = +25°C − 0.75 1.5 V TC = −40°C − − 2.5 V 0.2 − − V Pulse Width = 1ms to 2 ms, ITM = 5Apeak Duty Cycle ≤ 2% ITM = 15.7Apeak − 1.0 1.5 V − − 2.0 V VD = 7V, Gate Open TC = +25°C − 6 40 mA TC = −40°C − − 70 mA VD = 7V, RL = 100Ω VD = Rated VDRM, RL = 100Ω, TJ = +100°C Peak On−State Voltage Min Gate Controlled Turn−On Time tgt ITM = 5A, IGT = 20mA, VD = Rated VDRM − 1 − μs Circuit Commutated Turn−Off Time tq ITM = 5A, IR = 5A − 15 − μs TJ= +100°C − 20 − μs VD = Rated VDRM, Exponential Waveform, TJ = +100°C, Gate Open − 50 − V/μs Critical Rate−of−Rise of Off−State Voltage dv/dt .530 (13.4) Max .143 (3.65) Dia Thru .668 (17.0) Max K G .655 (16.6) Max .166 (4.23) Heat Sink Contact Area (Bottom) A (Heat Sink Area) .150 (3.82) Max
