Title:
TRANSIENT VOLTAGE SUPPRESSOR HAVING TEMPERATURE PROTECTION
Document Type and Number:
WIPO Patent Application WO/2021/012938
Kind Code:
A1
Abstract:
A transient voltage suppressor (TVS) provided with temperature protection, comprising a housing (1), a cover plate (7), a TVS chip (2), a first lead-out electrode (5), and a second lead-out electrode (3), and further comprising a thermal cutoff (4). A first electrode (41) of the thermal cutoff (4) is electrically connected to the first lead-out electrode (5), a second electrode (42) of the thermal cutoff (4) is electrically connected to a first electrode (22) of the TVS chip, and a second electrode (21) of the TVS chip (2) is electrically connected to the second lead-out electrode (3). The TVS chip (2) and the thermal cutoff (4) are accommodated in a cavity formed by the housing (1) and the cover plate (7), and the first lead-out electrode (5) and the second lead-out electrode (3) are led out from the cover plate (7). The solution uses a thermal cutoff to protect a TVS from overheating. The heat generated during the failure of the TVS causes the thermal cutoff to fuse, thereby separating the damaged TVS from the current and preventing a fire. The embodiment has the characteristics of a simple structure, stable and reliable products, and so on.
