Schottky Barrier Diode Characteristics

This example shows generation of the current versus voltage curve for a Schottky barrier diode. Define the vector of temperatures for which to plot the characteristics by double clicking on the block labeled 'Define temperatures'. Then double click on the block labeled 'Generate Characteristics'. The datasheet for this device gives Vf = 0.4V when If = 10mA, and Vf = 0.65V when If = 100mA. The ohmic resistance is set to one over the gradient of the datasheet I-V curve at higher voltages. The temperature dependence is then modeled by selecting the default energy gap and saturation current temperature exponent values for a Schottky barrier diode. The plot produced by this test model can be used to validate the implementation against the datasheet I-V plots.
