Abstract: The 5 V bidirectional TVS device was designed, and the effect of N+ implantation and annealing process on forward and reverse voltages was analyzed. By optimizing the resistivity, the bias of forward and reverse breakdown voltages was decreased from 1.3 V to 0.1 V, and all dynamic parameters meet product requirements. As a result, the symmetry of breakdown voltage of 5 V bidirectional TVS device was optimized.

Key words: breakdown voltage, ion implantation, anneal
