These formulae address the Debye product whatsoever temperatures. The more elementary formulae presented additional down give the asymptotic behavior inside the limit of reduced and high temperatures. For off state stress protection by deep p-areas is adopted, for on-state a thick oxide is employed in order to avoid the limits https://www.facebook.com/permalink.php?story_fbid=pfbid02KGWj8UX8Rrk4ogKd2gEe5HgZRg4VKfF2c7rBVhoySXPzAcAK4ofixkUYXwfAMirel&id=61562415773754&__cft__[0]=AZWS1AsmcRk3JzVrqdMgvZo384FyG5gZ_7SJAyZoMGFp5FIif75JhQ6xMiQvFNlJ32uFr1vl2g-_wcRxvbcPmc1AuuR6Xr58j610UFfvubyZiWGVeje45M0Jc6fIn7X8qYdkvgL1rAO0IqJ2pNQ0w2oclcuJujElHpSn1CNAZ74iudPlsQl4qC0-u-xXzrehrKnUUN-jx7KKIuQE0mOzqwYY&__tn__=%2CO%2CP-R
