Abstract
A design for an overvoltage protection circuit can be used to fabricate several different circuits incorporating different protection techniques. The design is suitable for use in a single device, which can be easily and inexpensively packaged and protected from the environment. Three terminal protection circuits can have three terminals on an upper surface of a substrate, or one terminal on a lower surface of the substrate, using a single modular design. Additional circuitry can be included to sense for high current conditions which are caused by overvoltages too low to trigger the normal overvoltage protection circuits.
