Abstract
A new semiconductor controlled rectifier which may be used to provide on-chip protection against ESD stress applied at the input, output, power supply pins or between any arbitrary pair of pins of an integrated circuit is disclosed. The structure which has the lowest breakdown voltage for a given technology is incorporated into the SCR enabling a SCR trigger voltage determined by the lowest breakdown-structure.
