John.I certainly appreciate any spice models, however, why not To include them in current LTspice designs is archiac. "collection" of devices that not one person in 1000 has in their collection. Who the heck would utilize a 2n11XX in a new design.Ĭertainly one of the problems we face are designs that people find in their Old devices ?.the /RoHS nonsense is to most breadboarders just nonsense. John, that is nonsense.why would I design a circuit that utilizes 50 year Try and John Woodgate, J M Woodgate and Associates, Rayleigh, Essex UK Have data from which they could be developed. Manufacturers, so if anyone wants further device models added, I may Sheets that I have for these devices.Yes, they were, and so were the BC157 series PNP devices. Versions for these devices as they are not shown on the detailed data I cannot say whether there were a, b, c, gain selected In addition, hal8000b, you have included the BC147 on the list which Iīelieve is a repackaged version of the BC107, but not the BC148 andīC149 which are the repackaged versions of the BC108 and BC109 On Fri, at 12:58 AM, John Woodgate wrote: There are lots of models to choose from now. I dont have plain BC108 or BC109, but have gain group A,B and C for these transistors so have left that out for now. OK, Geoff just included an alias to link BF194 to BF494 and BF195 to BF495. I realize that manufacturers don't necessary include spice models that are Ie., transistors that are not 50 years old.I, like most electronicĭevices that are outdated.but as technology advances 50 year old devicesĪrn't the best choice to include in models. John.I certainly appreciate any spice models, however, why not include Not all LTSpice models are for new designs. I substituted 2N2222 because I couldn'tįind models for the 2N3391. On eBay theyĪre still going for almost $1000. I'm not sure how long before that they were produced. ItsĪn IRD Mechanalysis Model 320 Vibration Selector. I have an old piece of equipment that I'd like to better understand. Here's an example of why to include old transistor models. I cannot say whether there were a, b, c, gain selected versions for these devices as they are not shown on the detailed data sheets that I have for these devices. In addition, hal8000b, you have included the BC147 on the list which I believe is a repackaged version of the BC107, but not the BC148 and BC149 which are the repackaged versions of the BC108 and BC109 respectively. Then they too could be added to hal8000b's list. If there is someone out there that has the skill to turn that data into realistic SPICE models I will put them up for viewing. If anyone is interested I have the original comprehensive Mullard (Philips) data sheets from 1968/9 scanned for the BF194, BF195 (and also for the BF196 and BF197 - not to mention the BC157, BC158 and BC159 the SPICE models of which are eluding everyone) So those could also be added to the list. I have checked their specs against the original data sheets I have for the BF194,5 and as far as I can compare they are the same for all the common parameters. If you have models (simplified) for the BF494 and BF495, I believe they are the same devices as BF194 and BF195. The list now includes, 2N1711 2N3391, BD911 BD912 and simplified models I'd also like to point out that Bordodynov also sent me a large file containing many other Russian and German transistors, which are included in the updated list. I have placed in /TEMP models some transistor, which You have not found. ~/.wine/drive_c/Program Files/LTC/LTspiceIV/lib/cmp To use this simply download standard.bjt and place this in your components folder and overwrite the existing folder.Ĭ:\Program Files\LTC\LTspiceIV\lib\cmpįor linux users this will most likely be:. If anyone has these files I will include them. The full list is order is in the text file models.txt 2SC5200 is the new name for 2SC3281 and 2SA1943 new name for 2SA1302 also included. These are Toshiba models and listed as Q2SA1015 and Q2SC1815. I have however found 2SA1015 and 2SC1815. Unfortunately, I've not been able to find all requested. These are taken from the various spice links Helmut provided and various other resources on the internet. The library includes modles from LTspiceIV and all other contributors models and now contains 579 models. It is listed in the files/lib/cmp directory under Updated_BJT_Models :. Subject: Increasing Standard BJT Library - Any Model Requests ? Is it too late to add the Toshiba 2SC1815 / 2SA1015 pair?
