The Dutch club also said it will look to recover financial damages from him.
PSV can expect a heavy fine after Uefa opened a disciplinary case against them following the incident.
The pitch invader, who PSV said entered the ground using a ticket bought by a friend, was already serving a national stadium ban until 2026 imposed by the Dutch football association.
He approached Serb Dmitrovic near the end of the play-off second leg at the end of February and punched him in the face. The former Charlton goalkeeper wrestled the man to the ground and stewards led him away.
Dmitrovic was able to continue as Sevilla lost 2-0 on the night, but went through 3-2 on aggregate.
The Spanish six-time Europa League champions will play Manchester United in the quarter-finals.
