In this work, a Josephson junction consisting of two superconducting layers sandwiching an insulating layer is explored, which is subject to the effects of thermal fluctuations. The precise expressions for the evolution of Josephson phase and the supercurrent through the junction are derived. A clockwise hysteresis cycle in the current-voltage characteristic curve is demonstrated mathematically. Additionally, the bifurcation of a planar limit cycle is established. The numerous stochastic thermodynamic properties of the resistively shunted superconducting tunnel junction system are described, considering the influence of three specific parameters: the conductance, the current bias and the noise intensity. Moreover, the probability density is characterized using the Fokker-Planck equation.
