NOTES :
1. Non-repetitive current pulse, per Fig.3 and derated above T_A = 25^OC per Fig. 2.
2. Mounted on 5mm² copper pads to each terminal.
3. 8.3ms single half sine-wave, or equivalent square wave, duty cycle = 4 pulses per minutes maximum.
4. Lead temperature at 75^OC = T_L.
5. Peak pulse power waveform is 10/1000 μs.
6. A transient suppressor is selected according to the working peak reverse voltage (V RWM), which should be equal to or greater than the DC
or continuous peak operating voltage level.
