Reg: Schmitt trigger and Zenor diode in eagle software

Hello,

I am Sudarshan. I amm new to Eagle software.
I need to use PTVS3V3S1UTR (Zenor diode - package - SOD 123W) and 74LVC2G14GW (pacakage - SOT -363). unfortunately I couldnt find them in the eagle library. So is there any way ?
Can I use another devices with same foot print/package ?. For example, my Schmitt trigger foot print is SOT 363. I could find diode with device name of BAS70-07S (BAS70-07) (its package is SOT363_Phillips). Similarrly for Zenor diode (Package SOD 123W), i found a diode with name DIODE-SOD123 (DIODE-) and its package is SOD 123. I am doing this because I just need to show dimesnions for PCB manufacturing (ignoring the functionalities).

Please let me know if I can use another devices with same foot print.


Thanks for the information,

Thanks and Regards,
Sudarshan.

You can use any device with the right package for dimensioning a PCB. It would be worthwhile learning how to edit and add packages and symbols - you will have to do it sooner or later. You can easily take a package from one library and put it in another and then add the package to the list of options to the "zener-diode" in the diodes library, for example. In fact there already is a SOD123 in the diodes library - you just need to add it to the zener part.

Just to add, there are some single logic devices in the 74xx-little library that should be a good starting point for your logic device.

Dear Keith,

Thank you very much for your answer.
How ever, I couldnt understood clearly on what you have said on adding ( "You can easily take a package from one library and put it in another and then add the package to the list of options to the "zener-diode" in the diodes library"). If you dont mind can you elaborate it more ? I couldnt understood how to add the package to the zener-diode. Thanks

You also have said "Just to add, there are some single logic devices in the 74xx-little library that should be a good starting point for your logic device." If you dont mind can you explain it bit further ?

Actually, Here in my case My Schmitt trigger "74LVC2G14GW " needs two inputs. The device which I found in the eagle library with same package is a diode (I have mentioned it in the earlier post). So, can I add new wires in the board/layout for the second input (as in schematic I will be having only one input )? and the same case with output (as it has two outputs).


Thank you very much for your valuable answer,

Thanks and Regards,
Sudarshan.

Hello again Keith,

I am using Freeware software, so can I add the diode package to the zenor diode ?

Thanks and Regards,
Sudarshan..
