NOTES
1. Non-repetitive current pulse per Fig 3 and derated above TA=25°C per Fig 2
2. Mounted on 5mm2 copper pads to each terminal
3. 8.3ms single half sinewave, or equivalent square wave duty cycle=4 pulses per minutes maximum
4. lead temperature at TL=75°C
5. Peak pulse powe. waveform is tp=10/1000us
6. A transient suppressor is selected according to the working peak reverse voltage(VRWM), Which Should be
equal to or greater than the DC or continuous peak operating voltage level
