    How to convert diode pspice model with 3 pin ?

    I have got PMBD7000 (3 pin diode) Pspice model from NXP Semiconductor web-site. This model contains 2 diodes and 3 pins in the diagram
    After automatic converting the spice file of PMBD7000(Lib->OLB) using Pspice model editor and put the library in the OrCAD Capture window, only 2 pin symbols are shown in the screen.

    I am wondering there are wrong conversion in the pspice model editor of OrCAD Pspice(Ver. 9.1).
    Please give me any advice to correct conversion ?

    I attached the spice file, symbol diagram and converted file(old).

    Thanks.

    can you put two diodes adn short one anode and one cathode of of them likewise in graphic symbol?

    Re: How to convert diode pspice model with 3 pin ?

    Yes, shreyas is right. What NXP is offering is individual diode model instead of full package model. You need to create a subckt consisting two diodes, short one pin of each and this would create 3 pin subckt model. Now if you create a symbol, you would get 3 pin symbol.
