This document summarizes the modeling of a Schottky diode component. It describes the key parameters in the SPICE model, and compares the simulation results to measurement data for forward current, reverse breakdown voltage, and junction capacitance characteristics. The simulation matches the measurement data to within 3% for most test points.
