If Pmax is what defines Imax, why then when the transistor is saturated, Imax * Vce < Pmax ? If the maximum power dissipation is not the limiting factor for the maximum current in a saturated transistor, what is? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
