The SOT-353 is a 0.65 mm pitch SOT23-5 type package. 

However, if you want to use the mfr. recommended pattern, you need to use the FP Designer module. 

You would normally start in the SOT23 calculator and set all the pads to the same value 0.60 X 0.60 then move the footprint to FP Designer to create a new 0.60 X 0.40 pad stack and replace pin 2. 

Also, edit the pad stacks to make the Paste Mask 0.50 X 0.50 on pins 1, 3, 4, 5. 

Takes about 4 minutes to make the mfr. pattern.

Hello,

I'm relatively new to this software, and I'm having trouble determining what category a SOT-353 falls into. The closest match I can find listed is a SOT-23, but SOT-353's are smaller than SOT-23's. Has anyone else encountered this issue?

For reference, this is the package I'm talking about: https://www.nxp.com/docs/en/package-information/SOT353.pdf

Thanks
