Description

Technical Field

[0001] The utility model relates to the technical field of patch TVS diodes, in particular to a TVS patch diode for vehicles. Background Art

[0002] TVS tube devices include through-hole packages, patches, unidirectional and bidirectional. TVS tubes are also called transient voltage suppression diodes. TVS tubes respond to voltage quickly and can suppress voltage changes. They are a type of diode device. The TVS tube is connected in parallel with the protected circuit. When the voltage exceeds the clamping voltage of the TVS tube, the TVS tube immediately starts to work and conducts, shunting most of the current to the ground through its own low impedance.

[0003] Using TVS to protect information equipment in automotive electronic systems is a convenient, effective and reliable way. The chip size of automotive TVS chip diodes is large, and it is difficult to ensure the accuracy of the chip position during welding, and a good assembly effect cannot be achieved.

[0008] As an improvement, the slots on the slotted copper substrate are concave slots, and the concave slots wrap around the chip.

[0009] As an improvement, the slotted copper substrate is made of copper.

[0010] (III) Beneficial effects

[0011] The advantages of the utility model compared with the prior art are: in the present invention, the slotted copper substrate has a slotted design, which can effectively limit the position of the chip, thereby improving the assembly effect; the slot is a concave design mechanism, which can effectively limit the chip, and the limiting effect can make the assembly process easier.
