A transient voltage suppressor (TVS) device includes a MOS-triggered silicon controlled rectifier (SCR) as the high-side steering diode and a silicon controlled rectifier (SCR) for the low-side steering diode. In one embodiment, the MOS-triggered SCR includes alternating p-type and n-type regions and a diode-connected MOS transistor integrated therein to trigger the silicon controlled rectifier to turn on. In one embodiment, the SCR of the low-side steering diode includes alternating p-type and n-type regions where the p-type region adjacent the n-type region forming the cathode terminal is not biased to any electrical potential.
