  We study the $Y=0$ triplet extended supersymmetric model in the light of the
recent Higgs boson discovery. We calculate full one loop Higgs mass spectrum in
this model where the possible doublet-triplet mixing is considered in the
charged Higgs sector. This mixing changes the prediction of
$\mathcal{B}r(B_s\to X_s \gamma)$ in this model, compared to the MSSM. The
constraints from the $\sim 125$ GeV Higgs along with $\mathcal{B}r(B_s\to X_s
\gamma)$ are incorporated to find out the allowed parameter space. The lower
bounds on the third generation squark masses coming from 125 GeV Higgs are
rather week in this scenario compared to most constrained supersymmetric
scenarios, e.g. a 200 GeV squark mass is still possible.
