Abstract
A semiconductor die has ESD clamp circuits that include vertical PNP transistors. The vertical PNP transistors include at least one region in a semiconductor substrate that is substrate isolated from a biased portion of the substrate. The ESD clamp circuits include a resistive element that is electrically coupled in a conductive path between the emitter and base of the vertical PNP transistor. The PNP transistor is conductive during certain ESD events to discharge ESD charge from the emitter to the collector.
