Claim:
1. A bi-directional bipolar junction transistor (BJT) structure, comprising: a base region of a first conductivity type, wherein said base region constitutes a drift region of said structure; first and second collector/emitter (CE) regions, each of a second conductivity type adjacent opposite ends of said base region; wherein said base region is lightly doped relative to said collector/emitter regions; the structure further comprising: a base connection to said base region, wherein said base connection is within or adjacent to said first collector/emitter region; wherein said first and second collector/emitter regions and said base region define a bi-directional BJT, and wherein a connection to said base region of said bi-directional BJT via a second transistor having a first input/output (I/O) terminal connected to said base connection, and a control connection coupled to said first CE region.
