Hi,

Let me look into this. Is there a reason why the 1.2/0.8 length on the package drawing is not sufficient?

Inserting the screenshot from the datasheet to illustrate the dimension Marcoo mentioned. If this answers the question, may you please close the thread?

Hi, based on the drawing show that part of the lead will be under the boy. 1.2/0.8 is the length from the lead toe until the edge of the body only. i like to confirm the total full lead length including the lead length under the body if possible.

Hi, pg 60 land pattern shows a maximum size of 1.5. I do not currently have the information for the section under the body but it is not critical to the land pattern.

The best I can do is measure a device but i cannot give you a max or min deviation. Is that acceptable?
