Generally, you cannot exceed any of them. When the transistor is in saturation, the max current may not get to Pmax. When the transistor is cut off, Vce is at max, but dissipation is very low. The real dissipation appears when the transistor is not in saturation and there is considerable current. > Can someone explain to me what defines the maximum current via a > transistor? > Since Imax * Vce != Pmax... > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- FCC Rules Updated Daily at http://www.hallikainen.com - Advertising opportunities available! -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
