AUIRS21811S www.irf.com ? 2009 international rectifier 11 parameter temperature trends figures 4-16 provide information on the experimental performance of the AUIRS21811S hvic. the line plotted in each figure is generated from actual lab dat a. a large number of individual samples were tested at three temperatures (-40 oc, 25 oc, and 125 oc) in order to generate the curves. each line in the graphs consist of three data points (one data point at each of the tested temperatures ) that have been connected together to illustrate the understood trend. the indi vidual data points on the curve were determined by calculating the averaged experimental value of the parameter (for a given temperature). 110 135 160 185 210 -50 -25 0 25 50 75 100 125 temperature ( o c) turn-on propagation delay (ns) typ. max. min. 110 135 160 185 210 -50 -25 0 25 50 75 100 125 temperature ( o c) turn-off propagation delay (ns ) typ . max. min. 12 15 18 21 24 -50 -25 0 25 50 75 100 125 temperature ( o c) torn-on ris e tim e (ns ) typ. max. min. 9 11 13 15 17 -50 -25 0 25 50 75 100 125 temperature ( o c) turn-off fall time (ns) - typ. max. min. figure 7. turn-of f fall time vs. temperature figure 4. turn-on propagation delay vs. temperature figure 5. turn-of f propagation delay vs. temperature figure 6. turn-on rise time vs. temperature downloaded from: http:///
