A semiconductor component includes a semiconductor substrate (110) having first and second portions (111, 112) with a first conductivity type, a transistor (120) at least partially located in the semiconductor substrate, and a switching circuit (150, 350, 650, 850). The transistor includes (i) a first doped region in the first portion of the semiconductor substrate and having the first conductivity type (ii) a terminal, which includes a second doped region having a second conductivity type and located in the first portion of the semiconductor substrate and over the first doped region, and (iii) a third doped region having the second conductivity type and located in the semiconductor substrate below the first portion of the semiconductor substrate and above the second portion of the semiconductor substrate. The switching circuit is electrically coupled to the third doped region to adjust the bias of the third doped region.
