The standard bounds on the active-sterile mixing ($\\sin^2 \\theta$) from SN arise from SN1987A energy-loss, requiring $E_{\\text{loss}}<10^{52}~{\\rm erg}$. In this work, we discuss a novel bound on sterile neutrino parameter space arising from the energy deposition through its decays inside the SN envelope. Using the observed underluminous SN IIP population, this energy deposition is constrained to be below $\\sim 10^{50}~{\\rm erg}$.
