AI Technical Summary
Technical Problem
Existing plastic-encapsulated TVS is prone to damage when subjected to continuous overvoltage or lightning strikes exceeding specifications, leading to continuous overheating and potentially causing a fire, posing a safety hazard.
Method used
A power module surge protector is designed, comprising a bare TVS, a plastic housing, a trip electrode, and a trip assembly. The trip electrode and the pre-exposed bare electrode are quickly disconnected when the bare TVS fails, and the trip assembly isolates the solder joint to prevent continuous heating.
Benefits of technology
It improves product safety and reliability, reduces production time, and increases product consistency and reliability.

Abstract
The utility model relates to a surge protector for a power supply module, and belongs to the technical field of lightning protection. The power supply module surge protector comprises a bare chip TVS, a plastic package seat, a tripping electrode and a tripping assembly. The bare chip TVS is provided with a first pin and a reserved bare electrode; the plastic package seat wraps the bare chip TVS through injection molding, and the first pin and the reserved bare electrode are exposed; the first end of the tripping electrode and the reserved bare electrode are soldered to form a soldering point, and the second end is a second pin; the tripping assembly is located between the plastic package seat and the tripping electrode, can be inserted into the separated welding point, and is used for covering the welding point and separating the first end of the tripping electrode from the reserved bare electrode. According to the power supply module surge protector provided by the utility model, when the bare chip TVS fails, the welding point of the tripping electrode and the bare chip electrode can be quickly disconnected so as to be separated from a main circuit, fire combustion caused by continuous heating of the bare chip TVS is avoided, and the safety and reliability of a product can be effectively improved.
