1. A method for modeling an electrostatic discharge (ESD) breakdown current in an ESD protection device comprising a diode including an anode and a cathode, the anode comprising a first conductivity type diffusion layer, and the cathode comprising a second conductivity type diffusion layer, the method comprising:

  • defining a first proportional constant based on a circumference of the anode of the ESD protection device and a second proportional constant based on an area of the anode of the ESD protection device; and

    deriving a dual first order equation by sampling circumferences and areas of anodes of two ESD protection devices.
