Note 1: If T>10 → T = 10 (sec), T/t>1000 → T/t = 1000
Note 2: If T>10 and T/t>1000, “Pulse Limiting power (Single pulse) is applied
Note 3: If Vp<Vr (lp<lr or Pp<P), Vr (lr, P) is Vp (lp, Pp)
Note 4: Pulse limiting voltage (Current, Wattage) is applied at less than rated ambient temperature. If
ambient temperature is more than the rated temperature (70°C), please decrease power rating
according to “Power Derating Curve”
Note 5: Please assure sufficient margin for use period and conditions for “Pulse limiting voltage”
Note 6: If the pulse waveform is not square wave, please judge after transform the waveform into square
wave according to “Waveform Transformation to Square Wave” information.
Waveform Transformation to Square Wave
1. Discharge curve wave with time constant “t” Square wave
2. Damping oscillation wave with time constant of envelope “t” Square wave
3. Half-wave rectification wave Square wave
