Abstract
Disclosed are bidirectional ESD protection devices capable of solving a breakdown voltage mismatch (BV mismatch) phenomenon while securing operation stability by providing a high breakdown voltage. The bidirectional ESD protection device includes an isolation region between an anode region and a cathode region, and the anode region and the cathode region may face each other with the isolation region in between. Accordingly, the bidirectional ESD protection device realizes high-voltage bidirectional characteristics without adding a mask, is minimized or reduced in size, and solves problems such as a breakdown voltage mismatch and instability.
