Many current and emerging electronic applications require transient voltage protection on the low value range (for example 5V to 80V breakover range) along with low capacitance values for lower signal distortion on communication circuits. Prior art has used surface breakdown or offset buried region design concepts, however, they are more complex to build and manufacture due to problems like leakage. Thus, there has been a need for a bi-directional or unidirectional TVS device design having low BV values, good surge capability and medium to high IH (holding current) levels with reasonable wafer manufacture-ability while fully compliant with the most demanding customer specs concerning capacitance and surge needs.
