As we learnt in

Positively charged electrophiles -

Chemical species having capacity to attack e- rich portion of substance.

- wherein

H^{+},Cl^{+},Br^{+},NO^{+},NO_{2}^{+},R^{+}, 

 

Electrophiles are electron deficient species among the given H3O+ has  lone pair of electron for donation, thus, it is not electron deficient and hence does not behave like an electrophile.
