NOTES :
1. Non-repetitive current pulse.
2. Mounted on 2.0mm
2
( .013mm thick) land areas.
3. Measured on 8.3ms , single half sine-wave or equivalent square wave , duty cycle= 4 pulses per minutes maximum.
4. Peak pulse power waveform is 10/1000μs.
5. 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.
