You are very close. Follow that with an explode:

data["specificText"] = data["specificText"].str.findall('([A-Z]+_\d+)')
data = data.explode('specificText')

Output:

    id specificText
0  A1A     DEF_2122
0  A1A    DEF_87653
1  A2A     DEF_7654
1  A2A     DEF_2199
2  X1X     DEF_3542
2  X1X     DEF_0833
