At idle power, current levels shown to the left of the diskontinuity illustrate typically the high end leakage currentꢀ However, if lower leakage current  
levels are desired, they may be guaranteedꢀ In the clamping voltage region to the right of the diskontinuity, maximum clamping voltage is plottedꢀ
