Leakage Suppression of Low-Voltage Transient Voltage Suppressor

In modern electronics, as the supply voltage decreases, the protection devices for low-voltage application are gaining more importance. In this paper, two types of diode-based transient voltage suppressors are proposed for protection against electrical overstress and electrostatic discharges. The modified diodes show lower leakage under low-voltage and sharp $I$– $V$ transition after breakdown by only a few modifications on the fabrication process.
