A number of diode limiter semiconductor structures are described. The diode limiters can include a hybrid arrangement of diodes with different intrinsic regions, all formed over the same semiconductor substrate. In one example, a diode limiter includes a first diode having a first doped region formed to a first depth into an intrinsic layer of a semiconductor structure, a second diode having a second doped region formed to a second depth into the intrinsic layer of the semiconductor structure, and at least one passive component. The first diode includes a first effective intrinsic region of a first thickness, the second diode includes a second effective intrinsic region of a second thickness. The first thickness is greater than the second thickness. The passive component is over the intrinsic layer and electrically coupled as part of the diode limiter.
