PSpice A/D User Guide Creating and editing models October 2019 229 Product Version 17.4-2019 © 2022 All Rights Reserved. You can modify each model characteristic shown in the Model Spec frame with new values from data sheets. The Model Editor takes the new information and fits new model parameter values. When updating the entered data, the Model Editor expects either: ■ device curve data (point pairs) or ■ single-valued data depending on the device characteristic. For the diode, Forward Current, Junction Capacitance, and Reverse Leakage require device curve data. Reverse Breakdown and Reverse Recovery require single-valued data. Table 4-4 lists the data sheet information for the DbreakX model. To change the Forward Current characteristic 1. In the Spec Entry frame, click the Forward Current tab. This tab requires curve data. 2. In the Vfwd text box, type 1.3. 3. Press Tab to move to the Ifwd text box, and then type 0.2. Table 4-4 Sample diode data sheet values For this model characteristic...
