A new asymptotic estimation method (the H-method), which enables one to estimate the exact energy depth $E_{t}$ of a trap from the TSC peak and one of other coordinates of the higher side of the peak temperature $T_{\text{p}}$, has been proposed. From the establishment of this proposal and the L-method estimated from the lower side, more exact estimation of $E_{t}$ and a new application were made possible. The $m$ characteristics that provide a basis for judging whether a TSC curve is contributed by a single trap only or by multiple traps have been reported. They show a perfect flatness with the same $E_{t}$ value in the range from ca. 10% to 90% of 1/$m$ if the TSC curve is contributed by a single trap only. The $m$ characteristics of the coefficient $C_{i}$ (${=}E_{t}/kT_{\text{p}}$) have been proposed. A simple and convenient equation of the H-method and an expression of the asymptotic estimation method without $T_{\text{p}}$ are presented.
