This document provides a SPICE model and characterization data for the CLH02 general purpose rectifier diode manufactured by Toshiba. It includes: - The SPICE model parameters for the diode. - Graphs comparing the diode's simulated and measured forward/reverse voltage and capacitance characteristics. - Waveforms showing the diode's simulated and measured reverse recovery characteristics match closely. - Notes that the model has been verified against measurement data to accurately characterize the diode's performance.
