Code:
$ echo "J1705PEAN038TDMN" | grep -o "[0-9][0-9][0-9][^0-9]*$"

038TDMN

$ VAL=$(echo "J1705PEAN038TDMN" | grep -o "[0-9][0-9][0-9][^0-9]*$")
$ VAL=${VAL:3}
$ echo $VAL

TDMN

$

There's probably more elegant ways depending on what your string actually comes from. You could probably extract it - or several - from a file and whittle it down to TDMN, etc in one step.
