This document summarizes the PSpice model for a 6CWQ06FN Schottky rectifier diode. It includes: 1) A list of the diode model parameters and their descriptions. 2) An equivalent circuit diagram for the diode model. 3) Graphs comparing the simulated and measured forward voltage, junction capacitance, and reverse leakage characteristics. The summaries show good agreement between the simulated and measured diode electrical behavior.
