TVS (transient voltage suppressor) is a surge absorption protective component based on the principle of diode avalanche breakdown and is connected in parallel in the circuit when used.
When both ends of the TVS tube are subjected to instantaneous high-energy impact, it can suddenly reduce its impedance at an extremely high speed (nanosecond level), absorb a large current at the same time, and clamp the voltage between its two ends at a certain value, thus ensuring that the following circuit elements are protected from the damage caused by transient high-energy impact. TVSs are widely used in digital products, the automotive industry, communication and intelligent control systems, etc.

A TSS (thyristor surge suppressor) is a two-terminal overvoltage protective component based on the principle and structure of a thyristor and is used to protect circuit equipment under dangerous transient conditions. Taking advantage of the latest development in thyristor technology, JieJie Microelectronics adopts ion implantation technology on solid-state discharge tubes. Under normal operation, a TSS connected in parallel with the protected equipment shows high off-state impedance and a small leakage current, exerting no influence on the protected circuit. When breakover voltage (VS) is applied at both ends of the TSS, the TSS will conduct quickly and present a short-circuit state, thus releasing an amplified current to protect other equipment. When the current flowing through the component is interrupted or falls below the holding current (IH) of the TSS, the TSS resets and returns to the high-blocking state.
