WinSpice command line Spice for Windows. used as simulation engine by 5Spice Tutorials on Spice and Circuit Design 5Spice press release in Power Electronics Technology Spice Model/Subcircuit Download Pages Download Spice, Spice3 or PSpice® models (not HSpice, Spice2 or IBIS models). Please report bad links. New 5Spice Users recommend downloading Zetex's zmodels.lib to add discrete devices in the Library. International Rectifier for power MOSFETs. Place these files and any others that should be linked to the Diode, BJT(transistor), FET(all types), IGBT, SCR and TRIAC schematic symbols in Library subdirectories: Library\Diode_BJT_FET\{name of company} Place all other files in subdirectories: Library\Subcircuits\{name of company}. You may add as many subdirectories as you want. Library Location If using 5Spice v1.40 or later, see main menu TOOLS | REBUILD LIBRARY to find where the Library is located on your computer. For version 1.30, look up "file locations" in the Help index. Searching for Models but don't know the manufacturer? If looking for 2N2222, search the INDEX site or go to www.Google.com and search for        2N2222 spice    or     2N2222 model INDEX by part number ~14000 parts, with links to manufacturer's website 555 timer - A subcircuit for the TLC555, a modern lower power version, is available at the Texas Instruments site link below. This subcircuit requires specific settings to work in astable mode. An easier alternative is to use the one-shot in 5Spice instead (version 1.20 and up). Analog Devices Under "Models", select SPICE, then select a product catagory. Or search by product number, select product, then find "Design Tools" listing on product page. CoilCraft inductors Diodes Incorporated signal, power, zener. The MOSFET models do not include the drain to source diode that all power MOSFETs have. Use with 5Spice's ordinary MOSFET schematic symbol or use the Zetex MOSFET models instead. Fairchild discrete devices. Note: MOSFET models use non-standard syntax and are not supported. IGBT models only work with PSpice, not 5Spice. Click on entry in "Condition" column in device list to request model. Ferrite Bead PDF file download. page 6 shows subcircuit for lossy bead, graphs on page 2. The peak impedance is about 90% of the value of R4. Let us know if you find the way to change the center frequency of the impedance curve. General Semiconductor TransZorbs, diodes. note: most diode models are included with 5Spice. Company has been bought by Vishay. KEMET Download and install the KEMET Spice program to get their capacitor models. Run their program and select the capacitor you want. Move the graph cursor to the frequency you want the model to represent - you can lock the cursor by right clicking the mouse. Then go to the menu, select "MonitorXY", then select "Model Display". Press the Output List button and save the model file to the Subcircuits area of the 5Spice Library. Note: many file saves cause the KEMET program to show a confusing error message indicating a bad character in the name. The fix is to shorten the file name, then save. International Rectifier all models in single file Infineon  caution: subcircuits for MOSFET devices starting with letters BS... (formerly Siemens SIPMOS) do not use standard node order. User must change node order on .Subckt line to be drain, gate, source. Find subcircuit libraries at bottom of product pages. Intersil Linear Technology all models in single file. 10/15/2007 file crash bug: LTC1250, LT1168_IN, LT1168_OUT contain diode models with parameter EG set to a negative value. Value should always be positive. WinSpice will crash. Other Spice3 simulators will warn and set value to 0.1, far from normal 0.6. FIX: remove the minus sign. "EG=-0.61" change to "EG=0.61" Maxim crash bug: 5Spice prior to v1.30 and some other Spice simulators. Low supply voltage Maxim opamp subcircuits containing diode models with parameter N=0.1m (=1e-4, Spice default is 1.0). National Semiconductor individual model downloads convenient library of National op amp models Spice44.zip, not National site so may be older. ON Semiconductor large selection of Discrete and Power Control/Managment ICs. Ignore the Logic model downloads, they are not Spice models. After unzipping the download, notice it has 3 or 4 files for each device. Use the .SP3 files and delete the .SIN and .SP2 files (will fail or give incorrect results). Also delete the .LIB file if a .SP3 file is present. Some files with .TXT extension contain three models, each for a different version of Spice. Copy the model for "Berkley 3" or "Spice 3" to a separate file and give that file the .SP3 extension. 5Spice will ignore the .TXT file. Some files with .TXT extension have a single PSpice model - change these files' extension to .LIB Philips caution: for 5Spice prior to v1.30 and Spice3 in general, PSpice power MOSFET models require removing the "IS=0" parameter from the NMOS .MODEL lines to prevent crash in Spice3. Also the subcircuit for shottky diode BAS40L contains a typographical error in line "D1 1 2 BAS40L". Line should read "D1 1 2 BAS40-05V" Rohm discrete semiconductors STMicroelectronics MOSFETs, search site for "spice", then look for MOSFETs in results Supertex inc. has some ancient models for small power MOSFETs like 2N7002. Problem is the models don't include the drain to source diode that all power MOSFETs have. Avoid - use the Zetex models instead. switch mode power supply models, book, links excellent book by C. Basso. Starting with v1.30, 5Spice includes some demo schematics and models from his new 2008 book. Requires program registration to modify the model parameter values from the schematic. switch mode application notes from a high end Spice vendor in large .PDF file Teccor (now LittleFuse) - lower power TRIACs, SCRs, thyristors. Search site using "spice" as keyword. Note: the node/pin order of TRIAC and SCR subcircuits is not standardized in Spice. 5Spice includes symbols that work with the common node order, modify the .subckt line for other node orders. Put files under the Diode_BJT_FET section of library. Texas Instruments search site using "spice" as keyword. click on "analog and mixed-signal models". select area of interest. The program does not support the data convertor models.  For 5Spice prior to v1.20: Burr-Brown model files: these very old files end with a Ctrl-Z character which causes problems. To use, edit in Windows Notepad and delete the final character - it looks like a square box. THAT integrated circuits for audio applications Tyco Electronics (formerly AMP) connectors. see "View Models" link in upper right corner of page. vacuum tubes / valves tubes are 100 years old in 2004 Vishay keeps buying companies that make discrete devices, so has many discrete products formerly made by others. Select product catagory, then look for Spice under "Related Information" heading. Use the Spice3 or I-Spice models. caution: for 5Spice prior to v1.30 and Spice3 in general: some power MOSFET models require removing the "IS=0" parameter from the .MODEL lines to prevent crash in Spice3. Zetex discrete devices in single file. you only need the models library file zmodels.lib Spice model page On the Zetex Spice model page, right click the link to the zmodels.lib file and choose "Save target as...". If you open zmodels.lib in your browser and want to save it, be sure to save it as a text file, not as an HTML file! MOSFET models note To see all Zetex MOSFET models in 5Spice selection lists, download 5Spice v1.40 or newer.   Tutorials on Spice and Circuit Design eCircuit Center Use Spice to help learn circuit design - many example circuits with instruction for advanced students and professionals. Draw the schematic in 5Spice. Use 5Spice's Linear OpAmp in place of the opamp (.SUBCKT OpAmp) in these circuits. Component values and opamp's gain and pole frequency are in list at bottom of the page or listed in the circuit file you can download. All About Circuits electronics theory at the student level. Good for basics and areas you are not familiar with.
