TLDR : Answer Summary
The user is traveling to Vietnam from Bangkok on May 16th and returning to Bangkok for 3 nights on May 30th. They inquired about when to apply for the TDAC visa. Responses indicated that if they are merely transiting through Bangkok on May 16th (staying in the transit area without passing immigration), no TDAC is needed until they return on May 30th, when they must file for the TDAC visa for their stay.

Yes, up to 3 days before 30th May you will need to apply for TDAC

TDAC has a transit option. Make sure your departure airport knows

On the 16th, if you are transiting at the airport <- as in NOT needing to stamp in to thailand to catch the plane to vietnam (just staying in the transit area without passing passport control) you do NOT need to file a TDAC

You will need to have one filed when you come back in the 30th (even though it's just 3 days)
