How to extract specific line after regex match

Given a keyword Product data sheet how can I extract 3rd line only after that match.

For example, given below data, output should be XB4BW84M5

Product data sheet
Characteristics
XB4BW84M5

I have tried (Product data sheet)\r\n(.*?)(^.*\r\n){3} but, that is to find something preceeded by 2 lines then the key word but, it extracts all 3 lines I need the 3rd only

Use this pattern: (?<=Product data sheet)\r?\n.+\r?\n(.+)

Explanation:

(?<=Product data sheet) - assert that what's preceding is Product data sheet

If assertion is true, then it matches new line character with \r?\n, then matches whole line with .+, which is "match one or more of any characters", then again, in order to match newline I used \r?\n and then used (.+) to store in capturing group second line after desired string.
