A higher breakdown voltage transistor has separated emitter, base contact, and collector contact. Underlying the emitter and the base contact are, respectively, first and second base portions of a first conductivity type. Underlying and coupled to the collector contact is a collector region of a second, opposite, conductivity type, having a central portion extending laterally toward, underneath, or beyond the base contact and separated therefrom by the second base portion. A floating collector region of the same conductivity type as the collector region underlies and is separated from the emitter by the first base portion. The collector and floating collector regions are separated by a part of the semiconductor (SC) region in which the base is formed. A further part of the SC region in which the base is formed, laterally bounds or encloses the collector region.
